I’ve been working on a NixOS setup over the past few days and I just got BG3 to run a couple of hours ago. I had to switch from the Mesa driver to the AMD one, I can’t login to the launcher (CORS issue lmao), and it sometimes doesn’t launch at all. It’s still a bit of a WIP, but it did seem to run at least as well as it did on Windows when it worked. I’m hoping that having an ephemeral, config-based setup will save me a lot of this trouble in the future.

It’s technically possible but not recommended as the NTFS format has some quirks under Linux. Give yourself the best chance at everything working and do full reinstalls after a format.
