    currently using RTX 4070 Ti/ Ryzen 5 5600X.
    all the other settings are good enough i think(32GB RAM, 500TB SSD only for TSW, etc.)
    game settings are generic high, graphics high-medium, screen percentage 100%, 1920x1080.

    i gave up playing TSW about an year ago because of stuttering.
    originally using RTX 3060 / same CPU, but it stutters at the same moments after changing 4070Ti.
    so i concluded that problem was originated from low performance CPU.
    i know this issue is a problem that cannot be solved entirely but what i hope is just lessening the issue.

    which CPU is recommended?

    Is your OS and pagefile also on SSD?

    Did you have -dx12 active in steam? That will reduce stutters.

    And if wish to change you have to change to AM5 but then you need new RAM, CPU and Motherboard. In AM4 where you are now there is not a big step to make i think

    I’ve got a RTX 4070 and can play at High / Ultra with 60FPS with ease, so you shouldn’t have any issues. I think stuttering is more to do with the game engine itself and an issue no matter what.

    Right now I would say an AMD X3D chip. 9800x3d would be best, but 7800x3d is also good and cheaper if the price is a concern.

    And if you don’t want to change the platform completely, you can buy 5700x3d or its younger brothers 5500х3d and 5600x3d

    I'm running the same CPU with a 4070 Ti Super, running on Ultra settings apart from sky (Very High) and JetWash's mod on Ultra, 64GB RAM and a big NVMe SSD. Plenty happy with performance, 3 things that help:
    1. Run in DX12 as previously suggested
    2. Increase shader cache size as high as you can (I've gone with Unlimited)
    3. The shader cache clears every time the graphics driver updates, so don't stress that the first run on every route will have more stuttering while it refills the cache

    dummy question here.
    How do you opt for unlimited cache size, is it an in game setting?

    Thats not possible with a cpu replacement only. He has a AM4 structure what will result in nearly a complete rebuild of his pc. So AMD have different systems AM4 where he is and AM5 and the difference is the Motherboard Ram and CPU what costs a lot to change but i have to admit if you have the money change to AM5 is nowdays a good choice AM4 will run out of stock in a short time. then you can choose what you propose

    Is having an RTX 5090 pointless for TSW6?

    I’m using a RTX 4070 currently with a Ryzen 7 CPU.

    Yeah it seems that TSW is far more CPU limited than GPU limited, on a 4070 Super I was running it at Ultra 1440p with a 2x resolution scale so 2880p internal and was running just fine.

    This question depends on more than just whether it's useful for TSW! First of all, what kind of monitor do you have? Especially anything below 4K makes a 5090 pretty much pointless. Also, do you play other games like Cyberpunk? Those games benefit from the technologies this card offers. TSW doesn’t include any special Nvidia features like Raytracing or DLSS. If you don’t play those and only play TSW, I’d say absolutely not. It brings no benefit. It’s better to invest in a good CPU. A CPU contributes more because TSW relies more on processing power.

    thanks for all the answers!
    currently on phone, so here are some short replies:
    -considering full changing my computer.
    -DX12 doesn't help that much
    -OS is on the other SSD
    -shader cache size doesn't help too

    I'd say the sweet spot is an 8-core CPU that is running an all-core frequency as high as you can possibly get. For instance, I have an i9-12900KS with an all-core overclock of 5.2GHz and TSW really seems to like it.

    I think that could definitely be an option, but you really need to consider how the PC will be used! If you're using the PC purely for gaming, I wouldn't go with that choice instead, I'd recommend the AM5 processors, especially the X3D versions. These are by far the best choice on the market. A well-priced option is the 7800X3D, which is a processor that works well with practically any graphics card. That means you won’t need to buy a new GPU. The 4070TI is simply excellent and one of the most commonly used.
    If you also use the PC for other tasks like schoolwork, then what Brandon recommends is a better fit, because the X3D performs a bit less well on general workloads. But keep in mind that Intel doesn’t work with AMD and vice versa.

    My laptop is already enough for my daily task. Then X3Ds is the way i think. Thanks for detailed solution!

    ram: 8x4, i think?
    hdd and ssd are bit messed up. 256gb sata ssd for os, basic functions, and game launcher. 500gb nvme ssd for tsw, 2tb hdd for all the others

    I mean the memory profile in the bios? Are you running standard RAM speed or underclock/overclock.

    If you have 4 sticks that's going to cause issues, you will be running in single channel mode and from my previous experience with amd having all slots filled causes memory instability issues also.

    Nope. You will still use 2 channels but the length of the physical connection between the memory chips is increased causing an increased signal noise that the memory controller needs to deal with. This is what can cause instability, or force the controller to run at a lower speed. This is highly dependant on the luck you have with the memory controller in your specific chip and the quality of the motherboard.

    partially solved
    changed OS disk from 125 SATA to 2TB NVMe, and it got better. why?
    maybe next time before fully changing my PC, i'll change my RAM config to 16x4.

    change it to 2x32 GB you will get better performance in dual-channel than quad-channel (especially considering that your system is DDR4, dual-channel has a big positive impact on performance)

    As I said in my previous post, having 4 memory sticks doesn't make your computer have 4 memory channels.
    If his computer had 4 memory channels, he would want to use 4 memory sticks.

    You are right to recommend 2 sticks instead of 4, but the reason you gave to do it is wrong.

    RAM gives you any boost only in situations where it was previously lacking. If you have enough RAM for your tasks, then increasing its amount will give you absolutely nothing. On the other hand, increasing the RAM speed can provide some boost(depending on situation).

    I have a laptop with a RTX 4070 and a 24 core i9 / 8GB ram. I can run everything ultra at 160% at a decent 40-60fps (no stuttering) depending on route. Perhaps you need a beefier CPU.

    Hardware specs have almost 0 reduction on stutters caused by shader cache or tile loading. It will affect Fps and loading times. I went from ryzen 1600 to 3600 and 5700x3d/ AMD Rx5700xt 6700xt 9700, hdd to SSD and did not see any major change in stuttering reduction. The only real change in stuttering reduction is using tweaked ini settings as the ones from JetWash Lighting mod or my posts.
    There are some new gen games like Dead Space Remake that benefit from faster cpu in reduction of the micro stutter when loading new areas, however for TSW that is not applicable due to the nature of how the engine streams assets.
    I have even used a virtual drive of about 16 gb on the DDR4 ram to see if that helps, it made 0 difference.
    And as reminder, compared to other unreal games where the shader cache is created at launch, on tsw it is crated on the go while doing your first run on a route. This results in massive hitches and stutters on demanding routes but will get much smoother on consecutive runs afterwards.

    WOW! 500 TB SSD! That must've cost you a pretty penny. It is a tad bit overkill for just TSW, though.

    does ini settings you originally posted enough? i added more parameters mentioned at the replies, but i'm not sure they are good or bad

    Yup those contain the main core of settings in order to reduce stutter.
    I got a cheap SH gaming laptop with a gtx 1060 6Gb and i7 8750 and tested the same ini settings on it and it also removed 80-90% of the stutter and hitches, just like it would do on my much more powerful desktop pc with Ryzen 5700 X3d and Amd Rx9700.
    Also rember to adjust the memory pool values based on your Video ram. Going to high can cause out of Vram crashes.

    Just out of interest, what is a ballpark figure for a PC that would run TSW with no bother and also be future proofed for a few years?

    Thats not that simple to answer without further information.... Do you run Intel or Amd and What is the budget to spend? If you on AMD with a decent budget i will suggest AMD Ryzen 7800x3D but you need an AM5 setup. With AM4 you have to change to AM5 with a new motherboard and RAM. And with a new pc you should not choose for AM4. For a GPU is more like a budget question. A high end pc from scratch cost around 1500/2000€ and thats more a lower begin. And i will advise to choose for AMD in terms of Motherboard and CPU. The GPU makes no difference with AMD you can choose both. Why AMD? Its the best on the market. Intel is not that good anymore and they to expensive for what you get.

    Thanks, I have to upgrade my tower at some point for work, because mine is seven years old now. Was going to do it this year when win 10 support came to an end, but then they added it for another year, so I put it off again to save money. I might think about something a bit better that I can also game on when the time does come.

    Just out of interest, how bad would my old specs be for the game today? I know they are well out of date and underpowered, but just curious....

    Processor Intel(R) Core(TM) i7-7700 CPU @ 3.60GHz 3.60 GHz
    Installed RAM 16.0 GB
    Storage 932 GB HDD ST1000DM010-2EP102, 466 GB SSD CT500MX500SSD1
    Graphics Card NVIDIA GeForce GTX 1050 (2 GB), Intel(R) HD Graphics 630 (128 MB)
    System Type 64-bit operating system, x64-based processor

    Cheers

    Ah okay i understand! You ask how decent you Specs are.....
    GPU and RAM extreme below average what you need. 16GB of RAM is not what you need now days and 2 RAM sticks with both 16GB, 32 together is not expensive at all. You can replace that easy for around 120€ together.

    Youre CPU is not extreme Like the other stuff but i should advice to change that to prevent Bottleneck from a more modern GPU.

    You have to check your motherboard as well.

    Did you have look around or have a budget in mind?

    Thanks for the reply and info bud.

    I have not really had a look around, something for the new year I think.

    Reckon I could stretch to 3k once I know work is sorted for another 12 months.

    A question, which laptop is good for using Train Sim World 6? I know that a desktop PC is much better, but which laptop should be ideal for that train simulator? I would like to use that simulator in a more comfortable place.

    I'd say get something with a Ryzen 9 7945HX or better, and ideally at least a 4090, which should be broadly equivalent to a desktop 4080. A dedicated GPU with the most VRAM you can get is the main thing to look at for getting a laptop that'll last and won't start chugging when TSW7 comes along.

    Depends of the money you have and what settings you want to have in TSW? Start with a Nvidia RTX3050 3060 / 4050 4060 for High Ultra at 60 fps. You are willing to use some frame Gen tool like Lossless Scaling to set the game at 30 Fps and let the tool boost to 60 you can run anything stable on that or even older cards cards. I am using a mobile gtx 1060 for medium high and have almost solid 60 fps on Riviera.
    Also do your research and make sure that whatever laptop you chose does not suffer from overheating or else you will see half the performance due to thermal throttling.

    Okay thats a very nice amount. Please choose a balanced system and use components that are in line to prevent bottlenecking. So a decent CPU with a decent GPU.

    I really would not recommend turning on frame gen when the base FPS is anything lower than about 50. But 60 and above should be the aim. Be aware that the more sensitive you are to input latency, the worse a time you will have with frame gen.
    Also to get the most out of a lot of these technologies, always prioritise a VRR-capable display. It'll make the results look a lot better if you are going to use frame gen from a lower baseline.
