Hi guys, I was surprised to see that TS3 is still DX11 native. Is anyone having success using the -dx12 modification in the steam launch options. Also, I did briefly try TSW3 on xbox game pass and could have sworn it was DX12.. Either way, why are DTG reluctant to support DX12 officially?
In answer to your last question I’ve got no idea. Seems mad to give away free performance like this but there you go. I believe any games that are not native DX12 run on XBOX under a DX11 compatibility mode. FS2020 is the same at the moment. Finally, to complete my back to front answer, it works well using the DX12 launch parameter in Steam. For me at least the performance is much better.
Thank you for your response. I am ok on dx12 as well, but I still get the micro pauses every few seconds which has plagued TSW for a long time, it really bugs me that this hasn't been fixed. I run max fps at 80 and general hit that at ultra (RTX3080, 10700k).
Have you tried capping your fps? You can still get a really smooth experience but it seems to help with the stuttering. Mine is currently set to 60fps which is my monitor refresh rate. If you’re on a monitor with a higher refresh try capping the fps at 50% of what’s available…it could make all the difference.
They're probably reluctant to support DX12 "officially" because most players of the game won't have PC hardware that will take advantage of it (and will probably just make things worse) - you need a very beefy GPU and CPU for DX12 to have benefits (hence most people who try it complain it does not work, but on my 3080 it works wonders) Hence more support tickets, hence DTG do not want the headache. From my understanding they do maintain DX12 compatibility, because that's required for Xbox Series X|S. That's why Direct X 12 related bugs magically get fixed over time despite it "not being supported"
DX 12 was introduced on Xbox last year, I believe with the ¨Rush hour¨ update. All the other platforms still use DX 11, but on PC you can force DX 12 manually if you want to. There are no plans about making the game native DX 12 according to Matt who addressed this question in one of the TSW 3 release live streams.
Just a quick heads up, DX12 is causing flickering textures and shadows on scenery assets (like trees), but only in the new routes. The old ones work just fine. I tested this successfully multiple times, only the DX version makes a difference on solving this flickering. EDIT: I found a fix for TSW that seems to work wonder for those experiencing flickering in DX12. Add the following to engine.ini [/Script/Engine.RendererSettings] r.AmbientOcclusionLevels=1 The flickering seems to indeed be related to ambiant occlusion. The difference in unnoticeable to the eye in my case, and really seems to to remove the flicker entirely. [DTG Alex Edit] Please be aware editing files in this manner isn't supported by DTG and you should expect errors to occur if not done properly - if you try this specific method and find your game isn't working you delete the engine ini file and restart the game.
This is the best advice he can offer you. I did the same thing Remove this silly ini file and see how amazing the game is going to work.
Jetwash i think it has to do with r.AmbientOcclusionLevels that cause the flickering on directx 12 atleast that was what i read on this forum long ago old routes do not have it (before rush hour release i think it is)
It does not make a difference. Just checked on Dresden Hbf which shows this issue of black flickering polygons under DX12.
i replied to an old post (did not look at dates) and it could be better now in tsw 4 only noticed weird flicker at Dresden on Tharandter route and only at certain spots (started on foot in TSW 3)
Can't capture it, it's probably only happening on single frames. Like photographing a lightning strike, it's tough to time the screenshot exactly at 75 FPS. Set the date to October 12th, 8 am Clear weather. move outside the station (free cam) and move the camera a bit. You'll see large black polygons flashing up when moving. Also happens in cab view as you drive. Happens here, Ultra settings
still happens in TSW 4 but you have to stay at the same spot for awhile to notice it Tharandter rampe Dresden on foot seems like some weird shadow flicker further ahead if you press escape you probably notice that same effect more
I checked the other Dresden in Tharandter and it has something interfering with the shadowcasting. Like it's showing/hiding a shadowbox when the vertical angle is changed. But nothing weird with black polygons.
Think it's related to shadows yes. Definitely not happening on DX11. Tested on Nahverkehr Dresden btw, not Tharandter Rampe (which is ToDv3).
The weatheroccluder has a shadow enabled on the box, I dont know if that could cause the issue and I dont have much time to check more into it atm.
FWIW I tried it and the first time I free camm’d out of the station saw some random and very quick black vertical flickering. Once I’d passed through it it stopped and from then on I haven’t been able to re-create it. That was with ini changes though, not stock.
