Building a new renderer at HypeHype. Former principal engineer at Unity and Ubisoft. Opinions are my own.
Just pushed my WebGPU gfx backend to production.

Took 21 days to develop in total: native Dawn Mac + Windows first, then Emscripten for web. Runs really smoothly on the browser and the page load is super fast.

Zero issues on Mac, Windows or Chrome. Safari Tech Preview has some flickering tris.

User-generated content (UGC) in a nutshell: Massive spam of physics objects and skinned characters.

Runs at locked 60Hz well on modern phones. The problem is cheap 99€ Android phones with PowerVR GE8320 :(

Have been tuning HypeHype's custom GTAO implementation for two days: Morton sampling pattern, bilateral blur uses slope-based weight (instead of constant Z), 2x2 depth downsample passes use median (instead of max). Still work to do, but starts to look pretty good.

Testing video upload. Seems to have 50MB limit...
