People say you will have less problems with AMD but I am using a Nvidia GPU for years now (on Cachyos and Pop OS) without issues. I'm using Steam and Proton pretty much exclusively though.
Its an old card so I have no idea why I'm still struggling to get it to work. Is it perhaps because I'm using Xfce? I heard that Nvidia cards play better with Wayland although I haven't tested this myself.
But their happy path hasn't included proper wayland support for a long time.
Nvidia on laptops? Insert the famous Linus Torvalds meme here
I have an RTX 5070 (whatever the laptop variant is) and it absolutely rocks with almost everything I throw at it, running Ubuntu+Steam+Proton. I no longer worry whether a Windows game is going to run, because almost all of them do with good performance.
Or does your laptop have no other igpu?
My last Nvidia laptop was a Hybrid optimus laptop. I almost always ran it on the built in Intel igpu because of the really bad issues with the Nvidia cards. Video tearing, bad power management etc... I remember even switching the GPU wasn't easy... And performance wasn't as good either ..
