Does anyone here know whether/how this should affect WebGL rendering?
I'm developing a browser-based 3D game, and since a week or two ago I've noticed the rendering on mac/chrome is way slower than before. In fact my game now seems to be GPU-bound, where up to now it's always been CPU-bound. I think this started right around Chrome 94 shipped, but it's hard to downgrade and check. This is only on mac; PC performance doesn't seem to have changed.
TFA makes it sound like whatever is new in v94 is only about page rendering, not WebGL, but does anyone know for sure?
- flohofwoe 5y agoI've also seen a somewhat recent performance degradation on MacOS+Chrome in WebGL when the WebGL canvas is close to fullscreen size, and even for extremely simple scenes (it's inconsistent though, maybe related to remaining battery life?). My guess is that this is some problem in the interfacing between Chrome and macOS, or purely in macOS though, because other platforms are fine.
- chrishtr 5y ago(I'm the author of this blog post) The launch in Chrome 94 does not affect WebGL. It's just for HTML/CSS content. If you can reproduce the issue and can share a URL that does so, please file a bug at crbug.com/new for us to investigate.
- chrishtr 5y ago"should not affect WebGL" is probably a better way to put it. (No software has no bugs or unintended consequences...)
- fenomas 5y agoHi, thanks for confirming! The issue reproduces in Chrome 94 but not current mac/Firefox, so I think it's new (though with now way to downgrade Chrome it's hard to be sure). Unfortunately I don't have a shareable URL that reproduces it, but if I can find one I'll file.
