This is so cool. I switched to Linux and once a game runs performance is or at least feels comparable to Windows. With stuff like this improving it even further (and Gamescope, etc.) you can probably get a better experience gaming on Linux compared to Windows in some scenarios.
Idk but what I tested was outputting my mic audio over my headphones. Windows has a toggle for that in the sounds settings (I mean the one where your audio devices are listed, Windows has like 3 different sound settings) and on Linux I used Helvum to connect my mic to my headphones. Doing that on Windows made it really hard to speak because the latency was too high but on Linux, it was as if there was no latency at all and I could just talk normally. Unfortunately I don’t have any numbers but if there’s a way to test it, I’d be happy to do that.
MASSIVE problems. Especially on Wayland. Even more with a GPU that can’t keep up (Where FSR saves my ass, actually). But I’m used to the flickering and stuff now, and good story games (Like Metro Exodus) are optimized while looking fantastic.
