@brian To be honest, until and unless it becomes a problem for me, not really. KVM has the host CPU executing the VM instructions so timing on CPU instructions should product identical results. I have the VM setup as CPU and GPU pass through.

@daggermoon I just use a live boot usb,
mount /dev/sda1 (or whatever root is) /mnt
mount /dev/sda3 (or whatever EFI is) /mnt/boot/efi
mount --bind /dev /mnt/dev
mount --bind /dev/pts /mnt/pts
mount --rbind /sys /mnt/sys
mount --rbind /proc /mnt/proc
cp /etc/resolv.conf /mnt/resolv.conf
chroot /mnt
grub install /dev/sda (or whichever drive you want)
It seems like it would be pretty complex since I guess you need to disable the linux host from using the GPU, and do PCI passthrough in a VM that has Windows installed.@blobjim @shapis
This is all addressed by the Linux kernel and xml code specifying it for the VM.
And there's still the problem of the graphics needing to move around the system in order to get to the display instead of the display being directly connected to the GPU.
Again handled by the kernel and qemu, just requires a bit of XML code in the vm description. Not a big deal.
@lord_ryvan Interesting, haven't played that game so no experience with it. VirtualBox does do some things a bit differently, I was not able to get flyff to run it well, it runs but at about 3fps, where as it runs normally in kvm/qemu.
@thingsiplay I'm not ignoring, I am DISAGREEING, sorry if you're having a difficult time making that distinction.
@halfapage Anti-cheats don't generally care if they're running in a vm as long as they can insert kernel drivers.
@thingsiplay Ok well I've been doing this for as long as Grub has been a thing (since retiring lilo) without an issue, so not sure why it is a problem for someone you know but I'm going to stick with probably operator error.
@brian Ok, just for kicks tell me where I can get this.
