The problem is i am using Pop! OS and i don't use Zorin for gaming. If a update broke something i can't help
As for gaming, everything works here and have zero issues. I play games with full fps (Star Wars Jedi Fallen Order, Halo The Masterchief Collection, Mass Effect Legendary Edtion and so on). I too use the GloriousEggroll proton for steam and i use the GloriousEggroll runner for Lutris (i don't use anything else).
As for the nvidia driver, i don't understand why everyone has issues with 470 or 495 drivers. I installed everything manually on my system (downloaded the driver from the nvidia site and installed it) and i have again zero issues.
Steam launch great here too, no issues. Do you use .deb package or flatpak ?
