Doom 3: BFG Edition (Steam) either crashes or launches with weird graphics

Don’t think I’m using either honestly…optimus manager is only in the AUR right now and I’ve never installed it from there. Additionally I’ve never configured anything to the extent of what’s outlined in the optimus-switch guide here on this forum (Optimus Switch - Another Solution for Optimus Laptops). Looks like I’m only using the standard nvidia drivers:

$ pacman -Q | grep nvidia
lib32-nvidia-utils 470.63.01-1
lib32-opencl-nvidia-340xx 340.108-1
nvidia-utils 470.63.01-1
opencl-nvidia-340xx 340.108-1

No bbswitch installed either on my system…
