From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

How likely is this to work? KVM/VFIO Single GPU Passthrough (www.youtube.com)

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.

Here are the specs of my machine:

Motherboard: MSI B550 A-Pro

CPU: AMD Ryzen 7 3700X (no integrated graphics)

GPU: Nvidia GeForce RTX 3070

RAM: 32GB DDR4 3200MHz

Host OS: Manjaro

Guest OS: Windows 10 Pro

I used to use VFIO several years ago, but these days every game I want to play/ have played recently have all just worked out of the box with Proton. VFIO was always fragile, but it worked great when it did. It has the same problems Proton has with anti-cheat, since its still a VM. So your milage varies depending on the games you want to run.

That was my experience as well: ran VFIO for a couple years but Proton got good enough that the trouble wasn't worth it.
