Well gog doesn’t have a Linux client though, while steam really does a lot for Linux gaming. I used to prefer gog but I’m back to steam for now.

I had the same problem with bazzite and a GTX 1060. Initially I wanted to install steam os but it doesn’t support these older Nvidia cards as well. I always used the video cards HDMI which should work even without drivers. I switched to fedora but ultimately sold the card for an AMD Rx 6600 (which is working fantastically) because the drivers that support the 1060 are old and painful on Linux… Probably not what you want to hear, just my experience.
