They're garbage. They're bad enough that If you have an Nvidia GPU, it's borderline impractical to game on Linux. You can, but you'll be cutting framerates in half or more in many cases.
But you also have a pretty powerful card, unless you're gaming in 4K you could probably take a performance hit and not even notice.
I have a 3060 (prev: 1660 ti) and I can say that I've definitely noticed a difference in performance in lots of games.
