Turns out that those pesky shadows that won't go away no matter what you do to the foliage LOD or shadow Distance aren't shadows at all, but ambient occlusion. So the magic words were: Code: r.DistanceFieldAO=1 r.AOMaxViewDistance=20000 I also threw in this to improve the distant shadows, but it's hard to tell if it did anything: Code: r.DistanceFieldShadowing=1 For engine.ini noobies, you can find the file at Code: My Documents\My Games\TrainSimWorld6\Saved\Config\WindowsNoEditor\Engine.ini Create a new section titled Code: [SystemSettings] and add the config lines you want one at a time Peace at last, tree shadows going all the way around the curve: Here's my full system settings, for anyone who wants to copy.

Word to the wise: start small and increase gradually, step by step (lots of restarting involved here). INI edits for PC are great, but be sure not to overexert your hardware.

(Edited for updated settings)
Sorry, maybe stupid question, but are those .ini changes for a specific TSW version, or may they be used for 5 as well as 6? As we are currently in a change of the version
As I am looking at these system additions to the eng.ini file, wonder if they include JetWash's additions for use with GodMode? I have these in my ini file, though I cannot get GodMode to work even though I have copied the pak file over to TSW6.
GodMode works fine, but only on existing routes (until it’s updated). My mod already activates Distance Field AO so it’s likely this won’t do anything beyond what is already there. The draw distance of this stuff is hard coded into DTGs TOD system so Kat’s Better shadows mod is the only reliable way to have shadows render properly to the horizon. The downside of that mod is well documented so it’s a personal choice. Edited to add, I can confirm that I’m not seeing any difference to my mod with the extra line added relating to distance
I’m not sure you fully understand the mod if you view GodMode as ‘messing around’. The mod requires you to drag and drop 2 single files and copy/paste a single block of text to the main ini file, that’s it. It takes less than 30 seconds so hardly a chore! FWIW it works with DX11 as I’ve mentioned previously and the low preset (which again, contains the lighting changes only) is performance neutral and specifically designed for just that purpose.
Hi JetWash, will TSW6 also benefit your mod [Lighting & Visual Quality Enhancement as well as foobian's godmod as well as Train Lighting & LOD Fixes and others...] as you did for the previous versions or do you think that for now it's better to wait for its official release on 09/30/2025. Thank you for all the work you do for TSC and TSW and see you soon in your future projects!!! Kind regards, tof
Hey there. I answered the same question on the dedicated thread so hope you don’t mind me linking to that; https://forums.dovetailgames.com/th...-graphic-ep-v2-3-0.84738/page-19#post-1043851
The one thing I cant seem to get rid of is the shimmering, drives me nuts, tried every ini mod and option going and even at 2k its awful. Any ideas how to improve it?
Because the game still doesn’t use DLSS/DLAA the only AA solution we’re left with is TAA or FXAA, both of which suffer from shimmering. I get it still at 150% percentage at 4K base resolution although it is vastly reduced. My lighting / graphics mod helps as far as is possible, but 1440p isn’t that high a resolution really, so if you have the headroom on your GPU I’d suggest increasing your screen percentage as it will help
Yeah ive tried at 135 and it is better but obviously drops the fps a bit so il have a play around, see whats best for my system.
Hello and thank you, JetWash. Sorry, I hadn't noticed in my haste that a post on this topic was open for TSW6. Thank you and good luck. Have a good trip everyone with these three new routes while waiting for the next one... Lol Sincerely, tof
You should put those lines in alphabetical order in engine-ini so it's easrier to find what you need to find. And for others so they can see what they got and what they can try. Those text lines are quite mess now.
A question regarding audio, can one adjust the sounds through the engine.ini settings to maximise bridge reverb?
How to get Time of day- settings in game? I have that God mode and I have managed to add setting from there to engine.ini but all those "TimeOfDay" settings not working via engine.ini. I've tried add r. in front etc but no use. Passenger count work, track amd sleeper shadows work, so all "ts2." works, but all in "TimeOfDay"- section commands isn't. For example line TimeOfDaySystem.BloomIntensity=0 doesn't give anything. It's still 0.13 when I check it via god mode settings during a game. ts2.platform.MaxSpawnInterval=5 ts2.platform.MinSpawnInterval=0.1 ts2.platform.MaxSpawnRequirement=10 ts2.passenger.SpawnLimitScaleFactor=1 ts2.platform.MaxPlatformPassengerSpawnDistance=15000 ts2.platform.MaxStationPassengerSpawnDistance=35000 ts2.passengers.ForceStationSpawningOverride=1 ts2.passenger.HotSpawningDistancePadding=0 ts2.passenger.AdjacentStationsSearchDistance=0 ts2.passenger.MaxPlatformPassengers=600 ts2.passenger.DensityScale=5 ts2.passenger.DensityScaleNew=3 ts2.passenger.DensityScaleForceNew=0 ts2.passenger.ObjectPoolSize=200 ts2.passenger.ObjectPoolUseCount=5 ts2.dbg.Track.RailShadows.Enabled=1 ts2.dbg.Track.RailShadows.StartDistance=0.0 ts2.dbg.Track.SleeperViewDistanceScale=2.5 ts2.dbg.Track.SleeperViewDistanceScaleMax=1000 TimeOfDaySystem.BloomIntensity=0.1 All ts.2- lines works but that last doesn't.
r.DFDistanceScale=5 foliage.LODDistanceScale=5 Those numbers are going to stress the hell out of your gpu and are pure overkill. A starting point of =2 would be good, maxing on =3 if you have a PC with top end hardware.
Just a revisit of this thread. yesterday i accidently saved over my ini file and it died. gone. zapped. So i had to rebuild it all again. it works fine except, it seems to have killed every passenger. Platforms are utter vacant. Ive posted a picture of what they used to be like yesterday - nice and busy and active. Very alive. I use the code for passengers already shared on this thread (with thanks) but sadly its stopped working now. Here is my full ini file. Is there an obvious error Im making here, like a duplicate on/off toggle, or missing a necessary line? huge thanks _______________________________________________ [SystemSettings] r.Streaming.PoolSize=16000 r.Streaming.MaxTempMemoryAllowed=8000 r.UseAsyncShaderPrecompilation=1 r.UseShaderPredraw=1 r.UseShaderCaching=1 r.Streaming.FullyLoadUsedTextures=1 r.RenderTargetPoolMin=1400 r.Streaming.LimitPoolSizeToVRAM=0 r.Streaming.FramesForFullUpdate=2 r.Streaming.Boost=2 r.Streaming.HLODStrategy=2 r.GTSyncType=1 r.OneFrameThreadLag=1 s.ForceGCAfterLevelStreamedOut=0 s.ContinuouslyIncrementalGCWhileLevelsPendingPurge=0 s.LevelStreamingComponentsUnregistrationGranularity=10 s.LevelStreamingComponentsRegistrationGranularity=30 r.Streaming.NumStaticComponentsProcessedPerFrame=200 gc.TimeBetweenPurgingPendingKillObjects=200 ts2.dbg.JourneyChapterLockOverride=1 ts2.save.CheckpointsEnabled=0 ts2.RewardMonitor.ShowLowImpactNotificationsAsFull=0 r.D3D.ForceDXC=1 r.Shaders.FastMath=0 r.StaticMeshLODDistanceScale=0.001 r.SkeletalMeshLODBias=-2 r.Streaming.MipBias=0 r.LightMaxDrawDistanceScale=5 r.LightMaxDrawDistanceScale=5.0 r.MinScreenRadiusForLights=0.02 r.AllowLandscapeShadows=1 r.DFDistanceScale=15 r.BlurGBuffer=-1 r.DepthOfFieldQuality=6 r.SceneColorFringeQuality=1 r.BloomQuality=5 r.FastBlurThreshold=7 r.Tonemapper.GrainQuantization=1 r.Shadow.Virtual.ResolutionLodBiasLocal=1 r.Shadow.DistanceScale=10 r.ShadowQuality=5 r.Shadow.RadiusThreshold=0.01 r.Shadow.CSM.TransitionScale=2.0 r.shadow.CSMDepthBias=4 r.Shadow.PreShadowResolutionFactor=2.0 r.CapsuleShadows=1 r.CreateShadersOnLoad=1 niagara.CreateShadersOnLoad=1 r.AmbientOcclusionLevels=3 r.AmbientOcclusionRadiusScale=1.0 r.Upscale.Quality=5 r.TemporalAA.Upsampling=1 r.TemporalAASamples=4 r.TemporalAACurrentFrameWeight=0.1 r.PostprocessAAQuality=6 r.LandscapeLOD0DistributionScale=3 r.LumenScene.FarField=1 r.LumenScene.FarField.FarFieldDitherScale=100000 r.Lumen.ScreenProbeGather.Temporal=1 ts2.dbg.SteamParticleSpawnMultiplier=2.0 ts2.dbg.SteamParticleSize=0.7 TimeOfDaySystem.VolumetricCloud.GroundContribution=1 TimeOfDaySystem.VolumetricCloud.GroundContribution=1 TimeOfDaySystem.VolumetricCloudScale.BaseNoise=0.9 r.MotionBlurQuality=4 r.DefaultFeature.LensFlare=1 r.Tonemapper.Quality=4 r.Color.Max=0.85 r.Color.Mid=0.4 r.Color.Min=0.0001 r.ToneMapper.Sharpen=0.3 r.ParticleLightQuality=2 r.LightFunctionQuality=3 r.HighQualityLightMaps=1 masterSoundVolume=3.500000 foliage.LODDistanceScale=10 r.foliage.DistanceScale=10 foliage.DitheredLOD=20 r.FoliageCullDistanceScale=4.0 r.ViewDistanceScale=5 grass.densityScale=4 r.Shadow.CSM.MaxCascades=8 r.Shadow.MaxCSMResolution=4096 r.Shadow.MinResolution=2048 r.DistanceFieldShadowing=1 r.DistanceFieldAO=1 r.AOMaxViewDistance=20000 ts2.dbg.Track.RailShadows.Enabled=1 ts2.dbg.Track.RailShadows.StartDistance=0.0 ts2.dbg.Track.SleeperViewDistanceScale=2.5 ts2.dbg.Track.SleeperViewDistanceScaleMax=5000 ts2.platform.MaxSpawnInterval=5 ts2.platform.MinSpawnInterval=0.1 ts2.platform.MaxSpawnRequirement=10 ts2.passenger.SpawnLimitScaleFactor=1 ts2.platform.MaxPlatformPassengerSpawnDistance=20000 ts2.platform.MaxStationPassengerSpawnDistance=35000 ts2.passengers.ForceStationSpawningOverride=1 ts2.passenger.HotSpawningDistancePadding=0 ts2.passenger.AdjacentStationsSearchDistance=0 ts2.passenger.MaxPlatformPassengers=600 ts2.passenger.DensityScale=5 ts2.passenger.DensityScaleNew=3 ts2.passenger.DensityScaleForceNew=0 ts2.passenger.ObjectPoolSize=200 ts2.passenger.ObjectPoolUseCount=5
Primary cause (this will stop passengers) ts2.passenger.ObjectPoolSize=200 ts2.passenger.ObjectPoolUseCount=5 ts2.passenger.MaxPlatformPassengers=600 Why this breaks it The game can only ever create 200 passenger objects total But you allow up to 600 per platform TSW fails safely → spawns none Secondary hard stop ts2.passengers.ForceStationSpawningOverride=1 ts2.passenger.AdjacentStationsSearchDistance=0 ts2.passenger.HotSpawningDistancePadding=0 Why this breaks it You force station-only spawning You disable searching for adjacent stations You allow zero distance padding Result: the game finds no valid spawn locations
i would replace the offending lines in your .ini as follows: ts2.platform.MaxSpawnInterval=4 ts2.platform.MinSpawnInterval=0.3 ts2.platform.MaxSpawnRequirement=10 ts2.platform.MaxPlatformPassengerSpawnDistance=12000 ts2.platform.MaxStationPassengerSpawnDistance=20000 ts2.passengers.ForceStationSpawningOverride=0 ts2.passenger.AdjacentStationsSearchDistance=6000 ts2.passenger.HotSpawningDistancePadding=600 ts2.passenger.MaxPlatformPassengers=450 ts2.passenger.DensityScale=4 ts2.passenger.DensityScaleNew=3 ts2.passenger.DensityScaleForceNew=0 ts2.passenger.ObjectPoolSize=1400 ts2.passenger.ObjectPoolUseCount=30
I fixed it!! It was such a rookie error, combined with tired eyes. it was this line: ts2.platform.MaxPlatformPassengerSpawnDistance=20000 But I had actually used this: ts2.platform.MaxPlatformPassengerSpawnDistance=2000 It means they were only just spawning as I arrived, and by the time they were visible it was time for me to leave and this never see them. doh!
Right, having played around a bit recently and seen some game-breaking ini files on a few websites, I thought I'd get this guide in here for people regarding engine ini tweaks that take into account the limitations of TSW6 and UE 4.26: ⚠️ TSW6 Engine.ini Editing – What You Should and Shouldn’t Touch Introduction Editing Engine.ini in Train Sim World 6 can improve visuals, lighting, and smoothness — but it can also silently break gameplay if done incorrectly. TSW6 runs on Unreal Engine 4.26, which has hard engine limitations around: Streaming Actor loading Level of Detail (LOD) Gameplay logic (junctions, signals, AI) These limits do not scale with hardware. Even the fastest GPU or CPU cannot bypass them. This guide explains: Which settings are safe Which settings cause common breakages Why “bigger numbers” often make things worse How to tune visuals without breaking gameplay The #1 Rule of Engine.ini Editing If a setting affects loading distance, LODs, or streaming, it can break gameplay. Visuals and gameplay are not cleanly separated in UE 4.26. ❌ Common Mistakes That Break TSW6 1️⃣ Disabling Texture Streaming Code: r.TextureStreaming=0 Why do people do it? “More VRAM = sharper textures” What actually happens: Streaming logic breaks Gameplay actors don’t load correctly Manual junctions and signals fail silently ✅ Always keep this ON Code: r.TextureStreaming=1 2️⃣ Extreme View Distance Values Code: [/B] [B]r.ViewDistanceScale=10 r.ViewDistanceScale=50 r.ViewDistanceScale=75 Why do people do it? “To see everything far away” Why this breaks things: UE loads visuals beyond where gameplay logic is initialised Switches and signals exist visually but not logically Causes “ghost infrastructure” ✅ Safe practical range Code: r.ViewDistanceScale = 2.0 – 3.0 Anything beyond that is engine-unsafe, not hardware-limited. 3️⃣ Over-aggressive LOD Reduction Code: r.StaticMeshLODDistanceScale=0.01 Why do people do it? “To force the highest LOD everywhere” What happens: Gameplay meshes never downshift properly Interaction logic fails Junctions and signals stop responding ✅ Absolute minimum Code: r.StaticMeshLODDistanceScale >= 0.75 Below this is one of the most common causes of broken junctions. 4️⃣ Negative LOD Bias Everywhere Code: r.LODBias=-4 r.MipMapLODBias=-4 r.SkeletalMeshLODBias=-4 Why do people do it? “Sharper textures and models” Why it’s dangerous: Overloads streaming pool Causes stutters, pop-in, or partial loads Breaks actor initialisation under load ✅ Safe guidance Skeletal meshes: no lower than -2 Global LOD bias: no lower than -1 Mip bias: moderate negatives only ⚠️ Settings That Look Visual but Aren’t These settings affect gameplay indirectly: r.HLOD.* → Can collapse gameplay actors into non-interactive meshes foliage.*DistanceScale → Heavy CPU cost, can starve streaming r.Streaming.* → Misconfigured pools cause logic delays Rule of thumb: If it affects what loads when, treat it as gameplay-critical. ✅ Generally Safe Areas to Tweak These settings are mostly visual and safe when used sensibly: Color & Tonemapping r.Color.Mid r.Color.Max r.Tonemapper.Contrast r.Tonemapper.Sharpen Pitfall: Raising mid-tones too far washes out clouds and terrain. Guidance: Mid-tones around 0.40–0.42 are realistic Avoid pushing brightness through color alone Lighting r.SkylightIntensityMultiplier Bloom settings Ambient Occlusion strength Better than raising exposure: Use skylight to brighten scenes naturally. ☁️ Clouds, Fog, Atmosphere Volumetric fog quality AO scale (within reason) Cloud shadows These improve depth without affecting gameplay logic ️ Post-Processing Anti-aliasing (TAA) Motion blur (optional) Depth of field (light use) Safe as long as they don’t touch streaming or LODs. Why Hardware Doesn’t Change These Limits A common misconception: “I have a 4090 / 5090, so I can push higher.” Unfortunately: UE 4.26 streaming logic is single-thread constrained Actor initialisation happens in fixed ranges Visuals can outpace gameplay logic This is why, even on top-end hardware, it (the game) still breaks when unsafe ini values are used. ✅ Best Practices for Safe ini Editing Change one category at a time Avoid “mega presets” from unknown sources Be suspicious of: Huge view distance numbers Extreme negative LOD values Disabled streaming If junctions stop working: Check LOD and streaming settings first Conclusion Engine.ini editing in TSW6 is powerful but unforgiving. You will find various issues caused by: Over-aggressive LOD tweaks Excessive view distance values Broken streaming logic By respecting Unreal Engine 4.26’s limits, you can: Improve visuals dramatically Keep AI, signals, and junctions working Avoid silent gameplay breakage Smarter values beat bigger numbers. Now, as an example, here is the [systemsettings] section of my engine.ini for my 4070ti, 5800x, and 64GB of ram, giving me 60fps on the majority of routes I play: Code: [SystemSettings] ts2.save.CheckpointsEnabled=0 r.ViewDistanceScale=2.3 r.StaticMeshLODDistanceScale=0.80 r.LODDistanceFactor=1.15 foliage.LODDistanceScale=1.9 foliage.DensityScale=1.0 foliage.MinLOD=0 r.HLOD.DistanceOverride=0 r.HLOD.MaximumLevel=0 r.LODFadeTime=2 r.SkeletalMeshLODBias=-2 r.LODBias=-1 r.DetailMode=3 r.TextureStreaming=1 r.MipMapLODBias=-1 r.Streaming.Boost=1.15 r.Streaming.MaxTempMemoryAllowed=384 s.AsyncLoadingThreadEnabled=1 s.EventDrivenLoaderEnabled=1 r.Color.Max=1.50 r.Color.Mid=0.41 r.Color.Min=-0.0001 r.ToneMapper.Sharpen=0.2 r.Tonemapper.Contrast=1.05 r.FilmicTonemapper=1 r.BloomThreshold=0.9 r.SceneColorFringe.Max=1.0 r.DefaultFeature.AntiAliasing=3 r.TemporalAACurrentFrameWeight=0.18 r.TemporalAASamples=16 r.BloomQuality=1 r.BloomIntensity=0.95 r.LightFunctionQuality=1 r.SkylightIntensityMultiplier=1.08 r.DistanceFieldAO=1 r.DistanceFieldAOScale=1.1 r.EyeAdaptationQuality=2 r.ShadowQuality=5 r.Shadow.MaxResolution=2048 r.Shadow.DistanceScale=1.1 r.Shadow.CSM.MaxCascades=4 r.VolumetricFog=1 r.VolumetricFog.GridPixelSize=6 r.VolumetricFog.HightQualityLighting=1 r.CloudQuality=3 r.CloudShadows=1 r.Reflections.Quality=2 r.SSR.Quality=2 r.SSR.MaxRoughness=0.9 r.MotionBlurQuality=1 r.DepthOfFieldQuality=2 TimeOfDaySystem.SunIntensity=74000 TimeOfDaySystem.MoonIntensity=900 TimeOfDaySystem.StarIntensity=35 r.OneFrameThreadLag=0 r.HZBOcclusion=1
It's aggressive, yes, but within Engine bounds and still provides 60fps on most routes in my trial runs. You can run it lower, say maybe 2 or even below 2 at 1.5. Anything above 1 will improve visuals up to the maximum. I've actually just compiled a more wordy version of the guide that explains things in a more professional tone.
