I noticed my Chrome was chugging it after switching to opencore and upgrading to big sur.

I have an i9 and 5700xt, neither which should be a problem, but things just werent as smooth as they were on Clover+Catalina.

Try this:

1. Go to chrome://flags
2. Change "GPU Rasterization" to disabled.

For some reasons, and I'm not sure if it's opencore, big sur, or the version of chrome. But disabling GPU Rasterization, really put a stop to some chugging I was experiencing.
