## Configuration Notes

- Running in DX11 mode (default) for best Proton stability
- DLSS enabled via STL (`USEDLSS=1`) - toggle quality in-game settings
- NVAPI enabled for proper GPU detection and DLSS
- Using GE-Proton9-25 for best compatibility
- MangoHud should show `API: VK` (DXVK translating DX11)

## Proton Compatibility

- ProtonDB: Gold rating, Steam Deck Verified
- Generally works well out of the box
- If issues arise, try Proton Experimental or latest GE-Proton
- Some users report display artifacts with certain Proton versions

## DX12 Option

If you want to try DX12 for potentially better FPS:
- Change `GAMEARGS` to include `-dx12` in the STL config
- MangoHud will show `API: VKD3D` instead of `API: VK`
- May need `VKD3D_SHADER_CACHE="1"` in customvars for shader compilation
