The NVIDIA drivers are a constant source of problems compared to AMD. I’ve had updates completely break some games, so that if I want to play my whole library of games I have to alternate between driver versions.

I have a small windows install on a second SSD that I dual boot with. Most of my games work on Linux so I rarely have to boot over.

A lot is going to vary depending on the exact game you play, strategies and game mechanics can be super different. The best way is to find a character that you really like and focus on having a good time. It’s a genre built off of learning from failure, so you’ve got to try your moves in different situations and see what works. You can practice moves against bots to find what situations they work well in, and plenty of people post combos you can learn online. Just gotta lose a lot.
