Windows 10 Hyper-V Impact on Gaming


  • Service Provider

    Does anyone have any information or experience on using Hyper-V on a machine also used for gaming? Obviously this is for home use, not for business use, and it would be handy to have a Hyper-V environment at home and my only accessible Windows box is the kids' gaming system. But there is a lot of time that it is not used and Hyper-V could run there easily, it has more than enough power and RAM. Enabling Hyper-V means that the gaming environment is moved into a VM, however, so there is more overhead since Hyper-V is a type 1 / bare metal hypervisor. But that doesn't mean that the impact is large, MS has tuned this for this use case and the Dom0 retains some very efficient driver access and can talk directly to the GPU. Does anyone know if the impact is even noticeable? Obviously if guest VMs are running, that is noticeable. I mean when Hyper-V is enabled but no guests are running.

    I didn't see any on my desktop before switching it to Linux / KVM.

    Did you do any gaming on it?

    Nothing Uber intensive, just World of Warcraft. It ran fine. I didn't have my VMs doing anything too intensive. It all ran decently. My Video Card in that system is a Radeon HD 5750.



  • @scottalanmiller is not noticeable. It works fine, I played Far Cry and call of Duty and it was a precision with Xeon on it running Windows 10.

    That's good to hear. Having a Hyper-V host in the house would be really handy, especially for a lot of questions like we had today.



  • I have Hyper-V enabled and running a couple of VMs while playing 7 days to die with and it works. And my desktop and some of the components is old.

    I'm not even worried about running VMs while gaming, I'll do just one or the other.



  • I have been wondering the same thing because there are some older games that I'd like to run but Windows 10 breaks the DRM and the game crashes or won't launch.

    This won't fix anything. This is still Windows 10, just with the extra overhead of Hyper-V.



  • I've enabled Hyper-V on Win10 on my personal desktop computer before I put it away, and I noticed literally zero impact for gaming... and you're not really going to either.

    The FPS stayed exactly the same.

    It's still not noticeable while gaming if you have sufficient RAM and CPU, unless you are using video memory via RemoteFX for your VMs, then yes it is noticeable.

    Back when I did this I had a few VMs running for some labs when I was studying for the MCSE. I kept them running sometimes when I was gaming and FPS and responsiveness stayed the same.

    Great, I plan to do this today then.

    That's crazy. But with prioritization and enough overhead, no reason this wouldn't be true.



  • Take a backup of the machine as is. Then, try. See what its like. Have fun!
    If all goes tits up, restore the backup.

    No impact with hyper-v enabled on Windows 10 from what I could see.
