    Lol no, R* didn't scale back on the physics to allow for better graphics. Graphics and physics don't have much in common anyway - one will be mostly CPU and the other will be mostly GPU. They scaled back on realistic physics because it got in the way of fun for many players.

    Nope. That's the point you completely seem to miss. TSW is filled with badly made, unoptimized assets. They look bad and cause bad performance. Many of these are known, confirmed examples. It's not a performance vs graphics problem. It's simply a quality problem. TSW could be much better both visually and performance wise if proper care would be taken when creating assets.

    They scaled it back to allow for far more interactive objects, including pedestrians to be rendered at once within a scene. They've openly said that. It was to have more density of stuff going on to make the game look more realistic in other ways while reducing the realism in ways people would notice less. Players ADORED the more detailed physics not just because of the realistic parts of it, but also because of the ways the system could be broken to allow for emergent gameplay. GTAIV's multiplayer was constantly full of people having competitions, for example, for how far across the map you could launch your car, Skyrim Giant-esque from a particular set of swings in not-Brooklyn, even years after GTAV launched, because one of the biggest complaints of players was the kinds of fun the sequel removed, like setting up a human domino rally on a staircase.

    Also, when it comes to certain features like Raytracing, it's not a clean GPU/CPU split. CPU load spikes when a game's raytracing is turned on, and you will still see bottlenecking of RT performance if you have a lower end CPU. (I learned that one the hard way when I thought a mid-tier Ryzen would be fine as long as I had a beefy GPU and had to stick with raster rendering until getting a CPU upgrade)
    Hell, when GTAV launched on Gen7 consoles it had its own hardware bottleneck on graphics unrelated to either CPU or GPU in the form of I/O speeds. The game couldn't read the data fast enough over one SATA interface, hence the way it streamed data from one DVD while the other had to be fully installed to the XBox or PS3 hard drive - and the resulting "one neat trick" on 360 to eliminate texture pop-in which was to install the play disc to an external drive, so then for one thing, your DVD drive didn't sound like it was trying to take off, and for another, the USB interface could read the data far faster than the optical drive could, resulting in an immediately noticeable effect on the game's otherwise slow pop.

    I'm not arguing it's not filled with simple issues to solve, like rendering hundreds of passengers visible onscreen per coach in out of service stock in sidings, using up a bunch of texture memory and the like for something which objectively should not be there. But while it's inarguable that there are optimisation problems in TSW, and that UE5 has some workarounds for some of the core engine issues with UE4, the fact remains that to get something that runs without many of TSW's issues you essentially need to be designing something that better works within the framework of what Unreal Engine fundamentally was built to handle. Hence things like all the complaints about Obsidian's RPGs in UE5 not having "Real" seamless open worlds like Bethesda's do. Of course they don't, when you try that in UE, you run into all sorts of performance problems. (Even running a simple UE5 graphical overlay on Oblivion, the performance goes to hell). Even in UE4 on consoles you can produce a 120fps raytraced tour de force of a corridor based shooter that very skilfully gives the impression at first glance of taking place within a larger world, but where the illusion falls apart the moment you stop blasting through it in a line and push up against the limitations. Running Train is pulling this off pretty well, because it's not trying to be anything outside of that box. Fundamentally all videogames are about "faking it", and how well you pull that off depends on how well you work within the predefined limits of the tools you have, which is why I am an advocate for the proliferation of more in-house engines wherever possible. They all have their strengths and weaknesses (Looking at you RedEngine and the Witcher 3 NPCs lacking appearance persistence between looking away and back at them) but when designed from the ground up for something, there's far fewer tricks the devs need to use to create the illusion they want without compromising it. That's the real fundamental root quality issue, and it's baked in the moment you make the decisions at the start of a project within your own set of limitations (financial, etc).

    "Lazy devs" is an appealingly simple explanation, but also "Lazy Devs" is how you get stuff which takes the path of least resistance to achieve something that looks great by not trying to do anything too far outside of what your off the shelf engine's designed for.

    0.9.2 Hotfix

    Features
    -Level, Distance Traveled, and Accumulated Points are now displayed on the Main Menu.
    Note: Because Distance Traveled is a newly added cloud save variable data, stats from previous runs will not carry over. Your stat will begin from zero. Apologize for inconvenience.
    -In the Evaluation screen, details showing your selected Difficulty Multiplier and the Train Model used during the run has been added.
    -Visual Improvements: Added a blob shadow effect beneath AI traffic car.
    -Pressing Shift + Middle Mouse Button will now instantly reset all camera properties back to their default values.
    -Stop tolerace on free mode increase to ±10m
    -Add new style of stop marker
    -Add an option to significantly reduce AI train spawning to improve performance on low-end PCs.

    Fixes & Adjustments:
    -Diagram 1677A Fixes: Fixed an issue where players could not proceed past the Kanamori home signal.
    -Diagram 1677A Fixes: departures from Ise Station are now 70 seconds earlier to balance the timetable.
    -Updated engine RPM logic DC85 series. When the torque converter is locked, the engine is now mechanically locked to the wheels.
    -Reduced overall damping and running resistance so trains should now maintain momentum better and lose less speed while coasting.
    -Resolved an issue where 3rd-party Mascon plugins caused conflicting button registration with Xbox Controllers. Xbox controllers should now function normally. (hopefully this is last time)
    -Fixed a HUD mashup glitch where the ZUIKI HUD would randomly display while using an Xbox controller.
    -Fixed a bug where the controller (B) button would fail to register on the session-end notification.
    -Clamped maximum forward speed to slighty faster for AI traffic to eliminate the "car centipede" reverse bug.
    -Fixed UI background stretching issues on ultrawide monitors.
    -Corrected inaccurate entrance/exit speed limits displayed on certain timetables.
    -Updated the entrance and exit speed limits for Takahashi Station.
    -Fixed various typos, misspellings, and translation errors.
    -Added a missing wiper mesh to static train models.

    -Downsized several non-critical textures (such as bolts, labels, etc.) and reassigned assets to different streaming groups to reduce VRAM overhead. While this should alleviate texture blurring, if you are still experiencing blurry textures on lower-spec systems, please try the following steps:

    1. Increase System Pagefile: Ensure your Windows virtual memory (paging file) has at least 2GB to 4GB allocated.
    2. Set your graphics settings and AI Train Frequency to Low or Medium BEFORE loading into a scenario to minimize peak RAM usage during map loading.
    3. Once the scenario loads completely, check if the textures display in correctly (not blurry).

    Dude, the issue is that you keep going into much deeper topics than what the issues with TSW actually are.
    And it's LOVE like this:
    [​IMG]
    When they can't get even basic material properties right. This is not a technical limitation. This is not a know-how limitation. This is not a performance concern. This is a full team of devs ignoring the fact that a single material property is set incorrectly. Something that could be fixed in a matter of minutes.

    Or how the boxcars in Clinchfield Railroad cause framerate drops because some badly set up animation or something along the lines. They even suspect the probably clause, because they used to mention it back in the day in a live stream. Probably another 15 minute job, yet never fixed through the years.

    And this is just two examples. And TSW is filled to the brim with LOVE like this, causing ugly visuals and bad performance. And these are easy quick fixes you would normally assign to an intern.

    Everything else like raytracing, virtual shadow mapping, etc are just extra. These are also important and areas where DTG is lacking, but these technologies or the UE4 vs UE5 differences are not the issue with TSW.

    Just popping in to say, I love the game. More depth with the sim side of things than I anticipated (wheel slip, penalty brakes, etc.) and I love how smoothly it runs. Finally, a train game without stuttering and frame drops. I know it's far from a "true simulation" in a technical sense, but I really couldn't care less. The feel is there. Ironically, it all comes together to make it more immersive for me than an actual full-on simulator.

    And the game isn't even finished yet. Provided the game performance stays up to par with more feature additions, I will follow this developer wherever they go in the train game space.

    I do like how Running Train also handles custom paints for each train, where its just as simple as dropping a texture file into the correct folder.

    The only issue I have with the system is that there's a fixed amount of custom liveries that can be in the game at once. I reckon it's easy to fix, bjt at the moment it means you need to swap the reskins you have installed if you have a lot of them you want to use.
    It feels like there's a new patch for this game coming out every day. A very nice change from DTG!

    After playing Running Train for the last few days I am physically unable to play TSW. And no I am not joking. The terrible lighting and other visual issues like the ugly distant haze and the super ugly distant trees as well as the stuttering (which is not constant but happens) is causing me to rage quit and go back to the better looking and 100% smooth running game with far better immersion.

    I hope DTG is finally getting their act together (doubtful) and release a MAJOR update with TSW 7. Otherwise...well TSW2Prototype 4ever.

    why do you think its that far from a real sim (and I would not call TSW a real sim for the most part either)?
    It may take some shortcuts but the end result is convincing and the game is still in EA and will be improved further most likely. We already got more patches from the solo dev then we get from DTG in many months.
    Expert locos for TSW might have more depth in the sense of failures and physics simulation but the question is always do you really want 100 different failures simulated, is the pure driving that much more convincing and is it worth that much money expecially considering all the bugs that are in every TSW product even Expert locos.

    That's literally a problem with like 25% of all UE games (Not including the shovelware) where they leave a bunch of stuff set to the engine defaults.

    I'm not trying to discredit RT at all, so don't misunderstand the phrasing there. I just assume as a layperson, and from the threads here, that a lot of things aren't being simulated to the level of other "simulator games" on the market (not just TSW, but Sim Rail and the like). I was expecting a more arcade-like experience in RT so I was pleasantly surprised at the inclusion of things like wheel slip, different weight behavior based on the consist (2-car vs. 4-car), etc. I have no idea what's actually being simulated vs. what is being "faked" in RT and it doesn't really matter to me. The game feels great.

    As to your other point about failure simulation and the like, yes I personally would enjoy that. I'm not exactly a fan of the state of TSW so you're preaching to the choir when it comes to cost and bugs, just check my recent posts.

    There's the thing, all levels of simulation from basically none to speak of, to deeply in depth realism are "Faked". It's just a question of to what degree and if it's close enough for a given person's tastes.

    Despite the fact that, the sounds in this game are not very good. There are 2 examples that DTG should pay attention to:
    1. The sound of a thump when departing. In reality, I've heard this sound on every train I've been on. TSW have nothing like this.
    2. Flanking sound. This is the sound of a real train, not the constantly stuttering, suddenly disappearing and reappearing LOVE like in TSW.

    Now I need to hop on an 80x unit in TSW as a passenger and wait around for departure to check for the cla-clunk noise of the doors a few seconds after it starts moving.

    This game is so well optimised I'd like to see a Mac version. I have an M4 MacBook Pro and I reckon it would play pretty well on it. And it would look amazing on its screen as well.

    I bought this game and I'm exploring it. I've been playing TSC for 8 years. I found it spectacular and very promising. These past few days I've been reading, researching, and I've come to my opinion: What the developer did was PLAN how the game would be, create clear plans and follow this line: What is important to have a fluid, beautiful, and LIGHT game? Before developing a game, you need to create a meticulous plan, rehearse, reflect, and execute that plan, correcting problems along the way, as long as you use the right tools to offer a product that results in the highest satisfaction for players/customers. Profits become the INEVITABLE CONSEQUENCE. I don't know if I was clear, but this is what every company should do, whether in games or any sector of commerce, services, etc. Not to mention that all this was done by ONE SINGLE PERSON. This proves a few things: DTG, with around 200 employees and years of experience in the sector, failed to deliver what it should have in offering its product. It has its departments and hierarchies, like any other company, and they failed (bugs, resource-intensive gameplay, etc.). I think that, in 2026, certain things cannot be tolerated in the gaming world in general. If the developer who produced Running Train manages to attract good partners to expand the range of routes in the game, MAINTAIN and MODERNIZE this architectural technique over time, I'm sorry to say, staunch defenders of TSC and TSW, it will surpass other train simulators in a short time.

    It won't for me. Too little variety and fictional and because it's a single person developing it, I'll be bored before it's out of early access.

    It's brilliant, I'm enjoying it. But it's different to TSC and TSW and for me doesn't even begin to compete with it.

    Seems a lot here are only interested in pretty graphics which is fine if that's important to you. I'm interested in realism and variety and after the initial wow factor has worn off, I'll be back to playing TSC.

    Having a great time playing this hudless, you really have to be on your toes with the grades and speed changes. The physics feel really nice in this, even if supposedly implemented basically.
    I really like how the developer implemented the distant scenery, the trees on hill sides look amazing from the cab but on closer inspection they are low res. Dont care about this, as long as it looks good from the driving perspective. I think a lot of tsw routes suffer from not great distant/field scenery, that could definitely be improved i feel.
    Overall, having a great time with this sim, the scoring system is actually quite addictive....didn't think I be bothered about this aspect tbh!
    If this is the first offering from the dev, well, cant wait for the next.

    For real. Current plans for v1.0 are like end of 2027 if I believe. And that's not accounting for the future DLCs containing the currently "locked" routes.

    Though I wouldn't be surprised if after v1.0 he switches to making an actual real route instead of adding the branch lines to this one. But who knows.

    Just to preface this, I think Running Train is really cool and I'm very impressed by what they've achieved with a tightly focused vision for this game. However, if you dig a little deeper you can see how they've achieved this, and why it would be difficult to scale things up. Some observations I've made...
    • The rain and snow effects are really cool, and feel very immersive.
    • UE5's Lumen real-time lighting is a huge upgrade and contributes the most to the game's realistic look.
    • Real-time reflections powered by Lumen, look very good, although a little hazy.
    • The game has had 4 years to get to this point, plus however long it took to learn the tools.
    • 24 miles is very short compared to most TSW routes, so the whole map can be loaded into memory. Because of this there is no asset streaming, loading stutter is side-stepped.
    • If they want a longer route they will need to enable asset streaming which is likely to cause stutter.
    • There are fewer unique assets like POIs or regional Hubs.
    • There's doesn't appear to be any custom code written for the game. Everything has been made in UE5 blueprints, which limits you to very basic vehicle physics.
    • There is little interaction beyond the basic driving mechanics (no cab interactions)
    • No NPCs (On roadmap, but yet to see how good the implementation is or it's impact on performance.)
    • Cars only spawn on the roads next to the track
    • Cars only travel in a straight line then stop or de-spawn. They are not animated to turn corners.
    • The area is surrounded by mountains so less distance detail is required than a flatter region with further line of sight.
    • Distant trees are very simplified.
    • The game is optimised to look good from the cab, as there is no on foot option. If you use the free camera you can quickly find low quality assets and textures just outside of this perspective.
    • Track and junctions are simplified leading to gaps, overlapping and alignment issues.
    • Limited AI traffic.
    I hope it's clear I think these are smart choices that have enabled the dev to create to a very focused albeit limited game. However, it would be difficult to take this design and apply it on the scale of TSW. That being said there is plenty to learn from what they've achieved here.

    Please, don't. TSW have many many poorly made areas right next to the tracks. Maybe near the stations it's still more or less ok(on most of the routes), but in between... like Burbank on Antelope Valley. Sorry, I don't have a route installed right now, but maybe someone could take a screenshot of this "masterfully crafted" place, where there's a bare ground texture, over which levitate road textures, over which levitate cars.

    It is still yellow under the rain, meanwhile in TSW - "50 shades of grey"

    Judging by the fact that even TSG's top representative was quick to try to belittle Running Train, a subtle hint of envy might be inferred.
    Or something else entirely...

    Just having a go at demystify some of the speculation around of the game. No conspiracy theories ;)

    All games intentionally reduce detail in low visibility areas. It is not a criticism, just a tool for managing performance.

    Colours appear less saturated in rain due to overcast lighting which reduces the amount of light and makes it more diffuse.

    The fact remains that UE4 is an obsolete graphics engine and is no longer updated by Epic.
    I hope DTG don't think we'll have to wait years to build a more modern train simulator.
    And I'm not talking about transforming TSW into something else.
    I'm talking about something new.

    Glad someone else caught that. Seeing that person's numerous posts in *both* threads about this game really surprised me. Not sure if it's a culture thing or what but I found the tone to be really unprofessional. Won't be buying anything from TSG in the future.

    Is this your personal opinion, or are you making a statement on behalf of DTG ?

    One other thing I'll add, there are more reasons for stuttering/hanging/hitching in TSW than just texture streaming. Can't count how many times I've had the game hang just from advancing objectives when I'm at a standstill (i.e. before the "close doors" objective appears, or after decoupling prior to service).

    No one actually cares about the reasons behind it, they care about what they see and experience. Right now, Running Train is a better experience for a lot of people. If that ever changes (i.e. with the addition of longer routes, or passengers), people might have a bone to pick at. Until then, we will enjoy the buttery smoothness.

    I don't care that the route is fictional, I don't care about on-foot "gameplay", and I don't care about simplified physics when the "real" physics in TSW can cause trains to pop off the tracks for no reason whatsoever.

    8 hours of gameplay and I'm done with early access.

    If this is supposed to be competition it still has a while to go I don't see much replayablity in this game I probably won't touch it again until more is added.

    Looks great though.

    Agreed. There is a lot of shockingly bad scenery right next to the trackside on most TSW routes.

    Maik's posting history on the forum is very hit-and-miss, so I don't think it's worth taking what he says at face value. He makes good DLCs but his communication on here leaves a bit to be desired. I'm not much better, to be fair.

    Where are you reading that into it?

    Both Maik and Chris simply matter of factly explained for folks less familiar with the ins and outs of game development than themselves how each game accomplishes the particular things they respectively focus upon, and why TSW and RT are not an apples to apples comparison, as the particular corners each cuts to accomplish its results might result in a poorer product if applied to the other.

    They're not saying anything that's not true. Both games use tricks and cut corners. TSW probably even moreso than RT, since it is juggling so many more things that obviously performance suffers, I'd frankly say to an unacceptable degree, and I wish they'd stuck with keeping certain things closer to TSW2 when the performance was on average far smoother. But I am pretty sure TSW would get far more flak than it already does, however deservedly, if it pulled the same tricks RT does to run as smoothly as it does. There's nothing to be "jealous" of. It's not even trying to be the same thing.

    Yes, UE5 has some handy tools which automatically handle a bunch of the workload that needs to be painstakingly manually done in UE4, and deliver things like more realistic lighting and much smoother lod transitions, and UE4 will never be able to do those. But those alone do not make for a better end experience, and frankly I'd expect the more cynical folks here to be pouring more cold water on the idea that just having less work in that one department would lead to a better product that has more work put into everything else from DTG.

    As always, and as it should be, everyone interprets things their own way.
    You hold on to your interpretation, while I'll hold on to mine.

    Matt's comment:
    Hi Paul,
    Thought i'd jump in with some corrections :)
    First up - just want to say i'm super impressed with Running Train and absolutely have been asking the team to review it and challenge ourselves to learn from it.

    However - you've made some erroneous assumptions so let me correct them.

    The TL;DR here is - basically everything that makes RunningTrain look and feel better than TSW is specifically because of UE5, let me expand on that simple statement though.

    Stuttering - The UE4 maps don't like being this huge, all positions are recorded in terms of their offset from the world origin - but you can only get about 2km from the origin in any direction before you hit a limit. TSW uses something called World Origin Rebasing, this moves the origin dynamically as you go. Unfortunately this is an expensive operation computationally, and requires the world to just hang on a moment - hence, stutter. These are the stutters left over after you get rid of shader compilation etc etc.

    UE5 has done away with all that, with an entirely new and much improved way of creating large worlds that works without the need for any of this. So I would not expect hitching in UE5. It offers lots of other benefits too, it's a much much better system than the one in UE4 (which to be fair, was ahead of its time when it was developed also).

    Shadows - In UE4 we have developed our own little "trick" to push the shadows on tracks out to the distance (but only works on "simple" track like straights and curves), and we use Distance Field Shadows to get a more efficient approach on other simple objects - though this feature doesn't support Splines, which means lots of assets like walls, roads etc don't benefit. It's a great improvement however. After that, it's all about dynamic shadows, and those are super expensive to calculate, so those are the ones closer to the player.

    In UE5 you have Lumen. It can much more efficiently give the same effect as a fully baked level without the need to do so and while remaining dynamic.

    Side Note: You do NOT want to be asking for static baking as that means you only get one time of day per bake, and an end to dynamic time of day.

    Pop in - In UE4 we build and place assets based on their distance from the railway already, we define three "zones" - "touchable", "near" and "far". Touchable covers anything the player can specifically walk up to, Near covers anything the player can see from the boundary of the touchable area and far is anything out to the distance. The idea being that all the high detail loveliness is in the touchable, and the low detail stuff that definitely shouldn't be seen up close is out in the far distance. You should see the assets I believe named according to their usage in the editor too, and we will sometimes make specific touchable/near/far versions of an asset (if its needed) rather than using the touchable one out to the distance. If you load one of our levels in the public editor, you'll see these lolipops above each asset of scenery - green is a touchable asset, yellow is a near and red is a far. We did this to help make sure artists were using the right assets in each place, but it also demonstrates this in action. Beyond that, we use LODding, which is a dynamic system for raising and lowering the complexity depending on proximity to the player. I will certainly concede there are some issues with the way some of the assets have been "lodded" however part of the problem there is the need for this to be semi automated due to the volume of them - and that's what leads you to wonky windows. The choice of how to LOD is also manual, and what that asset looks like at each level. In an ideal world, lodding would be set up such that you never actually see it happen, with the lod switching to a higher detail version a moment before you can see that it has done so - however the flipside of this is that if you have an asset with say 6 lods on it (not uncommon) - that's like saying every asset takes 6 times the resources in memory etc. Ok not quite, because each one is smaller than the one before - but - more lods means more graphics memory being used. In some routes, you'll see flat "billboard" trees or cruciform (+ shape) out in the far far distance - which normally is fine, but sometimes some unfortunate lighting happening can mean they shine/reflect like a flat billboard and not like a tree, but it does mean you can see it happening.

    In UE5 you have Nanite. Nanite is basically automatic high quality lodding. You won't see it happen because it lowers or increases mesh complexity in subtle ways constantly which means that you shouldn't ever actually see it happening. You don't have the multiple assets for each lod either, just the highest fidelity asset. So that clarity you're seeing down the track, and no lod popping - that's all nanite, it's all still happening, it's just instead of having a small number of lods to pick from, it's got infinite "slidability".

    The ballast doing wonky things is a slightly different problem entirely. Basically there was an aspiration when the track was set up to have the ballast also be on top of the sleeper in some cases (as per reality) - but - the way the renderer handles this, those numbers get rounded up and down and suddenly things that were just under the ballast are all now over it etc and it looks like the ballast is moving. I am going to get the team to just abandon that idea and drop all ballast below the sleepers, which should resolve the problem.

    Bottom line - all those positives you're seeing in RunningTrain are fundamentally because of the foundations on UE5 and the improvements it brings (and of course, very good execution of them from the RunningTrain developers).

    I guess the next question is - well, if it's confirmed that TSW could look like RunningTrain if you just upgraded to UE5 - what the heck is taking so long, make it happen now!!

    You don't get the benefit of the stuttering improvement if you don't rebuild all the routes in the new world system - meaning no routes can be ported.
    You don't get the benefit of the lodding if you don't rebuild all the assets for Nanite - so scenery or trains can be ported.
    You don't get the benefit of Lumen unless you rebuild all your lighting (and restructure the locos0 - so no trains can be ported.

    Now - I should clarify "portability" is a variable scale. Obviously with infinite time and infinite people, anything can be done. But - what im trying to say is, it'd involve basically rebuilding all the content to use those features.

    I have huge huge respect for RunningTrain and love what it's brought to Train Simulation, but I did want to correct some of your comments in the video.

    Cheers!
    Matt.

    Ultimately, Tsw 7 will be released in three months, identical to its predecessors (there's nothing beyond this standard).
    Get your money ready, please.

    Ive been thinking a lot about how these two games handle their physics, and whether “more complex simulation” actually results in a better driving experience.

    Chris mentioned that RT only uses fairly basic physics. But is that really a bad thing? I might be completely wrong here, but when I am actually driving a train in both games, I do not feel a meaningful difference in how the vehicles behave. TSW simulates a lot of systems - which obviously costs performance - yet the driving experience itself doesn’t feel more realistic.
    It’s funny how DTG keeps highlighting features that Running Train supposedly “does not have”, yet those same features in TSW are often poorly implemented, half‑working, or simply not worth the performance they eat up. On paper, TSW has the more advanced systems: Passengers, dispatching, physics layers, complex train logic, but in practice many of these systems either behave incorrectly, cause stutters, or add nothing meaningful to the actual driving experience.

    Passengers? Yay, they often do not board at all, so I can drive an entire ICE service with every coach completely empty. NPCs casually walk across the tracks as if safety rules do not exist. Walking around is great in theory, but it also exposes how rough and inconsistent the game actually is. Building proportions are off (doors are noticeably too small), you are lucky not to fall through the map if you try to reach a collectible or see how assets were simply slapped together without any real cohesion. At that point, the “exploration” aspect does more harm than good. Honestly, a cab‑only experience would feel more polished than pretending the world holds up under close inspection.

    Which trees are "better"? Decide for yourself.

    Trackside "details".

    So while DTG likes to "brag" about having the “bigger feature list”, the reality is that a feature only matters if it’s done well. And that’s exactly where TSW keeps falling short.

    They are, but look incredibly realistic to me (from afar), something hopefully DTG can introduce. The near trees/foliage is also a step up in RT, TSW could really do with an upgrade of foliage, getting bored of seeing the same old trees.

    No worries. These were my last posts here and all over. All information about TSG (the real TSG) products will come from DTG marketing as usual though. I will never try to explain anything to the community again to get people the better idea how things really work so they could understand why things are like they are. No one is interested in that it seems. I learned that the hard way over the past 15 years now. All i got back is the hint (more a kick in the a** every time) that a developer is not allowed to have a opinion. Especially not over content from others. Fine, accepted.
