I’m on a 3060 on popOS and I’ve literally had one driver issue I had to rollback in the year I’ve been daily driving it.

This is a great response, would heed its points especially the yaml files.

Kinda agree. New graphics card is deffo a nuclear option. I’m running pop os and haven’t come across a game I can’t run as it’s got the Nvidia drivers built it. I’d probably try swap distro before buying a new card just in case it’s that. That’s just time and effort rather than buying something that ‘might’ work.

Probably also worth noting that valve are updating the proton drivers all the time, they want the entire steam catalogue to work on steam deck so I would expect every game to work on proton over time. Might just be a waiting game tbh.
