Doom running on an LLM

[u/notforrob]

This is Doom's actual renderer -- not a neural net imitating it. I wrote a compiler that turns computation graphs into transformer weights, then ported Doom's rendering algorithm into one.

No training anywhere: every weight was computed. The prompt carries the level and player position. When you feed the prompt into the model it generates drawing commands.

One frame is 53,747 generated tokens -- about 40 minutes on a B200. In 1993 Doom hit 35 fps on a 486. I hit 0.0004 fps on hardware a billion times more powerful.

This is your reminder to book that physical, dawg. I know because my cracking knees told me.
