SL3 Video Call performance

Been loving Mint on my SL3 15" and it but a couple apps have some serious performance issues, but most importantly video calls(zoom). The app itself doesn't think its using much CPU but htop/gotop show massive CPU spikes. I'm guessing this is a hybrid CPU/GPU issue but afaik the only thing I can do is wait for Kernel updates with better support.

Any recommendations on anything I can do in the meantime to get things running smother?
