F1 2018 corruption on characters in CG

[JaxLinAMD]

Operating System : Ubuntu 20.04
ASIC : Navi 10
DRIVER : amdvlk https://github.com/GPUOpen-Drivers/AMDVLK

setup steam
Set resolution to 1920x1080
Set quality to Ultra High
When entering time trial mode choose "Classic F1 Cars" otherwise corruption is obscured by car cockpit view.

add barrier in generated SPIRV can workaround this issue.

Which shader exactly?

We generate barriers when the orginal DirectX shader contains barriers. If there is none, this is a game bug.

[JaxLinAMD]

do you need the spirv file or renderdoc capture?
is the tool to convert dx shader to spriv wrote by yourself or thirdparty?

[doitsujin]

The SPIR-V so I can correllate it to the original shader.

*_edited.dis shows where I added barriers

[doitsujin]

Same bug as in F1 2019. We have a workaround for that already which we can enable for both games.

Hi @doitsujin thank you for this. I have steam proton environment now, could you tell me how to verify with the workaround you enabled? can I replace some dx binaries of steam proton?

[doitsujin]

DXVK binaries are located in .steam/steam/steamapps/common/Proton 5.13/dist/lib64/wine/dxvk and can just be replaced.

thank ya!

hi @doitsujin when building dxvk, I encountered following errors:

In file included from ../../../../../root/Downloads/dxvk-master/src/dxgi/dxgi_adapter.cpp:8:
../../../../../root/Downloads/dxvk-master/src/dxgi/dxgi_factory.h:13:41: error: ‘IDXGIFactory7’ was not declared in this scope; did you mean ‘IDXGIFactory2’?
13 | class DxgiFactory : public DxgiObject {
do you know how to resolve it?

[doitsujin]

The latest MinGW release (8.0, not to be confused with the GCC version which should be 10.2) ships up to date DXGI headers which are required to build DXVK.

thanks, it works :)
