    What’s wrong with a VM? I set up a Win10 instance in VMM right after I switched to Linux full time 10 months ago, but I had to use it exactly once to configure the RGB on my keyboard, and haven’t had a reason to boot it up since.

    From what I understood, it runs on ‘Bare Metal’ which means that it theoretically should preform just as well as if you booted into it, with the only overhead being the *nix which is minimal.

    I’m not saying it’s better, I’m honestly asking because I have very little experience with it.

    I used to dual boot back in the day, but that was when I was still on HDDs and the long ass boot times meant I usually just stayed in Windows if I was planning on gaming that day.

      That’s not how that works. I think your confusing bare metal with bare metal hypervisor. The latter is meant to mean a Type-1 Hypervisor, which KVM isn’t anyway but that’s another story.

      Without GPU pass through you aren’t going to get nearly the graphics performance for something like gaming. I’ve also had issues with KVM and libvirt breaking during sleep. It’s a lot more janky than you make out.

        Well it does seem to be a somewhat confusing subject, so forgive me for getting it wrong. I must have misunderstood or misremembered the information I read when setting up the VM 10 months ago. As I said, I have very little experience with them and was honestly just asking if it’s not almost as good. I wasn’t trying to ‘make it out’ to be ‘not janky’.

        According to Wiki, KVM " is a … virtualization module in the Linux kernel that allows the kernel to function as a hypervisor."

        I wasn’t aware that there was a distinction between a Hypervisor and a ‘Type-1’ Hypervisor, but now I know so thank you for clearing that up for me.

        Without GPU pass through you aren’t going to get nearly the graphics performance for something like gaming.

        According to this wiki, it seems like GPU passthrough is possible with KVM if your system supports IOMMU, mine does. But it looks like you also need a separate GPU to do that, so that answers my question about is it nearly as good as dual booting.

        Every game I have attempted to run has just worked and they seem to run just as good as they did in Windows, so I guess I’m lucky I don’t need to really worry about dual booting or VM’s. I was just kind of wondering if it would work if I did need it, since that seemed like it would be a lot simpler than booting into a different operating system.
