Current launch options to enable Raytracing / DLSS
Liemaeu Jul 25, 2023
What are the current launch options you need to set for Proton 8.0-3 to enable Raytracing & DLSS (with a Nvidia gpu)?

Is it still:

PROTON_HIDE_NVIDIA_GPU=0 PROTON_ENABLE_NVAPI=1 VKD3D_CONFIG=dxr11,dxr PROTON_ENABLE_NGX_UPDATER=1 %command%

or are some of them no longer needed?

VKD3D_CONFIG=dxr11 for RT with vkd3d-proton(DX12 games). its still disabled by default due to some rare games that crash with RT

PROTON_ENABLE_NVAPI=1 only needed when the game isn't added into the list of NVAPI games. that's for DLSS support then

enabling nvapi should also automatically hide nvidia gpu afaik.
no idea what the NGX updater parameter is.. never used it myself
