Raylib's author was very happy to announce that you can compile an entire raylib program with no dependencies other than, say, being a win32 app https://x.com/raysan5/status/1980322289527976202

Why not? The original Doom didn't use a GPU renderer. It should be possible to do simple 3d stuff in today's computers without it.

The original doom wasn't even proper 3d. It was a sort of 2,5d.

And sure you can do 3d rendering on modern CPUs. It's just better on GPUs. Like thousands of times better.

The main limitation of the engine is you couldn't have room over room. There is definitely three dimensions when playing the game.

Someone always points out how Doom wasn't "real 3D" like it's some sort of gotcha. Games are smoke and mirrors, it's all a 2D grid of pixels at the end.

Well yeah, a 2d grid of pixels also describes the result of rendering a 2d game. It matters how you arrive at that 2d grid of pixels, that's why you can't render Crysis on just a CPU. At least not in real time.
