It seems the influx of ever-ambitious Doom ports is never-ending. Yesterday, the existence of a project called "doomgpu" from jhuber6 on GitHub came to our attention, not long after we covered a separate Doom port for quantum computers dubbed Quandoom. The doomgpu port is much different and quite interesting for those interested in seeing how GPUs can be pushed toward non-graphics compute workloads. This port of Doom using the doomgeneric interface can be run entirely on a GPU under Linux so long as you have the LLVM C library for GPUs.
While the initial testing was done with an AMD GPU, the RX 6950 XT, and some coverage emphasizes that aspect, it's worth noting that this project should work on Nvidia GPUs, too. According to the original creator, "This implementation works on NVIDIA as well as AMDGPU. To use the Nvidia implementation, perform the same steps but with the nvptx loader and make target."
