Like the title says, what’s the main difference in performance between gaming on a windows VM with gpu passthrough on linux vs windows installed the usual way on bare metal? Talking about steam games and not online multiplayer with anti-cheat.
Because i would really like to get rid of my windows dual boot but for the moment i don’t want to get into linux gaming with proton etc…
Also, i would use this VM for other windows-exclusive softwares.
Thank you in advance!
So first of all you’d need 2 GPUs then. You can do it with a single one, but that will mean killing your DE when you start the VM and at that point it’s essentially working like dual booting, but with all the drawbacks of running in a VM.
Second of all, the main difference is … effort. You’ll be constantly fiddling with your config to get it just right (hint: you won’t). Some games just flat out refuse to run in a VM (granted, much of the same games will also refuse to run under Linux). I could never quite get rid of the CPU overhead. You need essentially twice the amount of RAM.
Also, /r/VFIO.
It may be annoying to setup, but once it works (with Looking Glass and such) it works very well. Have been running such a setup for years
