Doom’s game logic and renderer run in SQL at up to 60 Hz

The port runs Doom’s game loop at 35 FPS and renders 320×200 frames in SQL, with Python handling input, timing and display; multiplayer works too. It’s an unusual look at pushing a database beyond conventional query workloads.

What: SQLDoom runs the original Doom game logic and renderer inside a database, with Python handling input, timing, and display.
How: SQL game logic runs at 35 FPS and updates game state tables; the renderer reads that state and can produce frames independently, up to 60 Hz.
Why it matters: It demonstrates how database execution can host both application logic and rendering while separating the fixed game loop from frame requests.

Python drives SQL game logic while the SQL renderer reads shared game state. Sketched from the article's own text.
