How likely is this to work? KVM/VFIO Single GPU Passthrough
I've been wanting to make a proper switch over to Linux for a while now. I've currently have a dual-boot setup but still mostly use Windows. The majority of my games should work without fuss, but I'd like to have a simple solution for running the handful of things that don't work in Linux, such as my WMR VR headset and a handful of Steam games.
Linked is a video on Single GPU passthrough with KVM/VFIO, which I'd like to try.
Before I try this, I'd like a sense of how likely it is to work, and I'm wondering if there might be a better solution I don't know of. I'm also open to any tips you might have about speeding up the transition between Host/Guest OS.
I did it a few years ago, although I had an AMD GPU.
It works surprisingly well but games that require anti-cheat software (ex. Valorant) won’t work.
The only other good solution that wasn’t mentioned in your post is to just buy and maintain a dedicated windows box. Short of that, GPU passthrough is a great option
The only games that have anti-cheat on them actually support Linux anyway, just CS:GO. Not to mention, 77% of my hours in Steam games were spent in games that support Linux natively. 91% in games with ProtonDB scores Gold or better.
I used ProtonDB. You can log in with your Steam account and it will show the rating for each of your games, along with how many hours they are. It won't give the percentages for you, I had to calculate those myself, but the site got me 80% of the way there.
