gPu(doom)

The probability of Doom, running on a GPU near you: 1.

The Doom engine rewritten as WebGPU compute shaders. One GPU thread per screen column walks the BSP tree and draws walls, floors and sprites; the game tic (movement, collision, doors, lifts, pickups) runs in GPU kernels too. JavaScript reads the WAD, passes keys and plays sounds.
