The current status seems to be, chrome is also way ahead of firefox with webGPU. They just don't have the manpower anymore, so I would not get my expectations up high and just use chrome for games and co amd be happy if webgpu comes to mobile FF at all. Or petition mozilla into rehiring some engeneers..

And with this concrete project I cannot compare, because on my mobile nothing loads, neither on ff or chrome.

Hey all, if you’re willing to try again we just put out a fix that dramatically helps performance on some machines. Since this was a port to WASM from a native game engine, it turns out the issue was in our frame rate limiting code which wasn’t playing well with browser timing APIs: https://raverie-us.github.io/raverie-engine/

Same experience here, getting really low fps just moving around in an empty scene.
