This error message appears when i try to launch some steam games, some work (heartwood online) and some dont (Sect-Machina) , this problem has been going for a while and ive been looking a looong time for a solution. Help pls
im pretty sure i have up to date drivers, but i dont know how to Install Directx 11, neither enable 3D acceleration
If that doesn’t resolve it the next step, on a per-game basis, is to override the compatibility settings, stepping down the Proton version, until it hopefully works. I rarely need to get below Proton 6 before I have some success, but this depends on the games you play.
If that doesn’t work, you may need to customise the game’s launch command. I’ve rarely needed to resort to this. ProtonDB will sometimes offer some suggestions, but Sect-Machina unfortunately has no user reports yet.
In the game’s compatibility settings, one command you can set, which forces proton to use OpenGL (slower) instead of Vulkan (faster) is:
PROTON_USE_WINED3D=1 %command%
Alternatively, you could try disabling DirectX11, forcing use of DirectX9. If this works, this might run faster:
