If anything will get people to move to Linux, increases in gaming performance will. I know a couple of people who moved to Linux and virtually every game they play runs faster on Linux than on Windows. Also, some oddball USB stuff that wouldn't work under Windows works perfectly under Linux. They're not going back; they're more than happy using Linux as their daily driver.
The biggest problem for me was not performance in FPS, but the fact that no game worked out of the box on pop!os or bazzite. I want to install and play; not install, crash, rifle through the internet for 15 suggested fixes, implement them all, cry a bit, play, crash, and then give up. Until that problem is fixed I will sit tight on win10 for my gaming.
