WebGL performance drop in recent Chrome releases

Question

im not sure why (probably an update) but chrome has significantly lost performance while running some things I've made with three.js. I haven't worked on anything in a month and now that i've returned to my project i've found things are suddenly running much slower than they used to. I used to get a smooth 60 fps+, and now things are chugging along at 20 fps in one of my programs.

Just to be clear, I've changed absolutely nothing. I simply opened my projects a month later and the performance has dropped by 40+ fps, which is frightening. This is true for anything using three.js.

I'm wondering if anyone knows what the issue is.

This is an application I've made which has significantly degraded in performance, at least on my machine. There also strange shading behavior which has appeared on the shading of certain objects due to hidden lights(?).

I'm using the WebGL renderer by the way.

I'm using Three.js version r66, since there are no migration instructions to move to any higher versions on github.

Answer 1

Go to chrome://flags and make sure Override software rendering list is set to enabled. This will make sure the GPU-acceleration is enabled on unsupported system configurations
