I'm not sure what I should use it for though since I don't really run any windows applications other than games, and I use QEMU for that, only game that hasn't worked in QEMU is "Halo Infinite".
Why not use Proton?
The reason I don't use proton is because compability isn't 100%, whereas actually running windows gets you to a 100%, if we don't count games with predatory anticheats, but those don't work on proton either (For now).
I'm REALLY superstoked about Intels new HPG GPU's, it's rumored they'll have SR-IOV support, meaning I could partition the GPU to run both Windows and Linux at the same time. (There's support for it in my 11th gen Intel CPU on my work laptop, but the software isn't there yet, so I'm not certain it'll work)
