Original Doom launched on Radeon RX 6950 XT without using the CPU

Doom has long been used as a benchmark for performance, running it on extremely low-powered, old, or unsuitable hardware. Now, Doom has been launched on a Radeon RX 6950 XT. This might seem uninteresting, but the point is that the CPU wasn't used in this case.

More precisely, the CPU was present in the system, but the game was modified so that it worked solely on the GPU, without involving the CPU at all.

This Doom port, using the doomgeneric interface, can be fully launched on the GPU under Linux if you have the LLVM C library for GPU. Using the clang compiler, enthusiast jhuber6 successfully compiled and launched Doom with a single-threaded game logic (the rest of the visualization is multi-threaded). The specific Linux version used in this case was Arch Linux with kernel version 6.10.5. However, officially, Linux in general is required, so it is likely to work normally on any standard Linux distribution with the x86 architecture.

Unfortunately, there is only a screenshot available, but there is no video of the process, and it is unclear how well everything worked.

However, as in most other cases of running Doom, this is interesting primarily as an experiment.
