These screenshots show the difference of Windows 10 and DXVK.
The cars are rendered a lot darker.
The car windows are almost black.

After I experimented with the MSAA settings, I saw that DXVK can actually render the cars correctly.
The game starts with MSAA 4x. If I set MSAA to OFF, everything looks correct. If I set MSAA to 4x again it stays correct.

Software information

Dirt 3 Complete Edition
Ultra Settings

System information

  • GPU: Radeon HD 7970
  • Driver: Mesa git, LLVM 8.0.0 svn
  • Wine version: 3.16
  • DXVK version: problem also exists with current master

Apitrace file(s)

Putting the dlls in the game folder like described in the wiki makes the game crash on start.
However I honestly dont understand whats meant with "dont use apitrace with DXVK".
If DXVK is disabled, how can you see the issue then? Isnt it rendering with Wine's stock D3D11 implementation?
Also is a trace from Windows needed?
Im sorry for not having a trace ready yet.

This is a known bug with RADV when using MSAA. Affects GTA V as well.

Please test if this RADV patch fixes the issue.

I cannot test the game, it doesn't work on my Wine setup.
