zorin should recognize the gpu and ask if you want to use the proprietary nvidia driver. If you install proton afterwards it should work out for gaming but I don't use it for that and as I said its more about stability and out of the box than bleeding edge or best performance. I can't really say how it will be for gaming. Funny thing is my intention going forward is to paly around with bazzite and appimage as a way forward. mostly because I like the immutable thing.
