Since most people don’t use Linux, drivers and software aren’t usually developed for it. Although, a reasonable company would develop just in case or help you get a solution, it’s unusual. Most computers are supported, but there is very specific hardware that may not have support or you’ll find bugs.

I’d recommend you to search (and test with an USB in Live mode) about your hardware and ask in communities about this specific topics. There are music communities, movies, math, streaming, etc.

And no, I don’t think you’ll find anticheat support because most Linux users don’t want closed shady software modifying their kernel (but there are solutions being worked on).
