How Do I Enable Raytracing with Nvidia Cards?
I've did this for Proton games:
PROTON_HIDE_NVIDIA_GPU=0 PROTON_ENABLE_NVAPI=1
I remember it working before but now I'm not sure. Dragon's Dogma 2 is a game I've been testing it on and I have yet to get it to work. The option is always disabled. DLSS shows up fine though and I have a 3070 ti.

What am I doing wrong? It seems like every other game it refuses to register either DLSS or Raytracing.
