Is it a good idea to run windows in VM with gpu passthrough (nvidia RTX) for certain games, instead of dual booting?
Is it a good idea to run windows in VM with gpu passthrough (nvidia RTX) for certain games, instead of dual booting?
I've been dual booting Linux and windows for about two years now, but in those two years, I have never booted into windows, except by mistake.
This made me think about removing windows and just saving that wasted space for Linux. I only ever dual booted for the off chance the peer pressure to play anti cheat games was too great, but so far it hasn't.
For the off chance where I want to play a game that doesn't run well on Linux, is it a good idea to do that via VM instead of dual boot, or is it too much hassle? Will there be performance hit or any issues with those games?
You're viewing a single thread.
i've had good success with this but ofc ymmv. it can be hard to get your windows vm performance tweaking right and it can take a buttload of time. if you want best mitigation of anti-cheat risk and best performance then you should continue to dual boot imo.
Do you do this to play games with anti cheat? I read that some games detect that. Are there ways around it?
depending on how you virtualize your windows install, yes, there are ways to kind of "spoof" your machine details (like manufacturer, desktop instead of vm) but again, it won't be fool-proof and it might take a lot of time to get working well. i definitely have not tested that many triple-a windows games with anti-cheat because that's just not my gamer wheelhouse, but so far after spoofing some of my machine details (spoofed as a baremetal oem install) i haven't had any issues.
What hypervisor are you using?
I use proxmox and run a couple windows VMs for Remote Desktop. I’ve passed through nvidia gpus and even at point had a nvidia grid setup running splitting up a P40 across multiple VMs.
The nvidia gpu’s require several config options to ‘spoof’ a real desktop and prevent the code 43 error but windows still identifies them as virtual machines. I’ve never found a way for trick windows itself into thinking it’s stand alone.
for hypervisor i'm using libvirt+qemu. by doing this, a few lines in the .xml for the vm is all that is needed for me to enable some hyper-v feature flags to spoof to windows that it's not a vm. check to see if proxmox has some hyper-v features you can enable for this purpose.
