NVIDIA DLSS "Unavailable" on NVIDIA GeForce RTX 4090

[MOHAA2002]

nvngx_dlss.dll works on vkquake-rt but not on prboom-plus-rt.

You need an older version or RayTracedGl1 and nvngx_dlss dll to work properly with prboom-rt-1.0.7. Though you can still get the older dlss dll from here https://github.com/NVIDIA/DLSS/releases/tag/v2.4.0, you can't get the required RayTracedGl1 dll (v1.1.1) since the author removed it.

However I've compiled the RayTracedGl1 dll myself and uploaded over here: https://archive.org/details/raytracedgl1-dlss which should work properly with prboom-plus-rt v1.0.7
