Sadly, though, this game uses OpenGL, and RTX Remix has a lot of trouble overhauling those games. However, we may be one step closer to a Path Tracing Mod as Justin Marshall was able to implement DX12 and DXR to the official level editor of Doom 3.

I haven't looked into the specifics on why he chose to add a DX12 renderer, but maybe just going with Vulkan would have made more sense here, since RTX Remix itself uses DXVK internally to render those older games with added path-tracing anyway.

Plus I remember seeing that NVIDIA was looking into how to get OpenGL games to play nicely with RTX Remix as well, but no idea how far they got there right now.

RTX Remix has worked with DOOM 3 for awhile API is basically a suggestion now, everyone’s been reverse engineering their games to work with Remix

Thoughts on OpenGL, Vulkan, and DirectX 12?

DX12 portings of ID4 are already good enough: Release RBDOOM-3-BFG 1.6.0: Retro Revolution and Modding Mastery · RobertBeckebans/RBDOOM-3-BFG · GitHub

Video looks kind of choppy

Yeah, pretty bad showcase... And if you look closely the image is like a badly compressed JPEG. No idea what's up with that. Some bad reconstruction used in the process or something?

Looks like it's running in low resolution.
