When you enable HyperVisor, all those resources travel through hardware, then to the HyperVisor, and then to the Host PC that its been treated as Virtual. In normal conditions, while gaming, all resources travel through hardware to Windows Kernel and then distributed when needed. This type of visor does not affect host pc performance when vm are not running because everything is being handled by your host Windows Kernel. On the other hand, VMWare workstation,VirtualBox is Type2 Visor, that runs onTop of Host PC Kernel. When you run a VM, the primary kernel(Hyperv kernel) creates a new 'container' that runs the Guest OS Kernel on top of it, like Host Kernel but with limitations and not direct access to resources.

This consumes resources because EVERY resource goes through more processing, and because those systems wasn't optimized for gaming performance. That means that your pc runs a layer of Kernel that handles virtualization and then as a second Kernel the Windows 10 Host OS, and gives direct access to all resources. Vmware workstation is completely different. Its not about services, Everything happens in kernel level. If you disable the services, VMs no longer work properly though, because the software no longer has access to things like networking, USB, and physical storage volumes. VMWare does the same thing.Īll of the software that handles pass through networking and devices runs 24/7 unless you disable the services. If the Hypervisor is running in the background, it does take some resources away from the primary user facing OS, even with no VMs running. Hyper-V is a layer that runs beside your standard Windows install. It's possible that issue has been fixed over time.Īs far as I know, if you want to do work that involves Hyper-V, then run:Īnd after doing either of those commands, you'd need to restart.ĭoes anyone have any better info or links with regards to Hyper-V performance with no guest machines? Also, all the articles about it reference Windows 8 instead of the more-common Windows 10. While all I'm seeing online is anecdotal evidence, I would love to know the real-world impact. Because of this, Hyper-V reserves part of the GPU for virtualization even if it's not used and this reduces your gaming performance. Does anyone know of any sites or videos of folks that have done an assessment of the real-world impact of Hyper-V on gaming? From what I've seen, enabling Hyper-V in the OS means your Windows install is actually running virtualized on Hyper-V itself even if you don't have any VMs.
