GTA V ran in a browser via WebAssembly and WebGPU

On October 6, the site PlayGTA5.com briefly let users play GTA V locally in Chrome: Rockstar's RAGE engine was compiled into a 63 MB WebAssembly module of about 91,000 functions, with Direct3D 11 commands replayed through WebGPU. The unofficial project vanished within a day, and booting it required roughly 700 MB of data.
