Hello @Pixeldrifter825, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to https://github.com/ValveSoftware/Proton/issues/6573#issuecomment-5893872987.

NVIDIA GTX 1990 GPU
whatever I tried, these versions of proton will not let the game launch, it will just immediately closes when I press play. there was an issue with the shader cache, but I was able to get that resolved. I would like to ask if anyone else is having this problem because I have no idea if this is a compatibility issue or not.
