Hi, I am doing some tests as we might need to change our IT environement at my job. So I installed some guests in kvm. In General the vms run very well, only GPU seemed a bit slow, so I installed virgl 3d and the result is very nice for Linux guests, but i think there is no driver for 3d accel. for win10 guests yet.

My test for GPU was simply play a video fullscreen in the guest vms.

I compared with vmplayer then and was surprized how well windows guests run in it, even gpu with video playback.

So is it correct, that gpu performance of windows guests is handeled best with VMware and kvm is remarkable slower than VMware?

KVM host for testing was an old gentoo box with a core2duo and a radeon R7 (cap verde). Is it possible to get similar gpu performance with open source kvm? Gpu passthrough is not an option.

Or will new hardware (actual server to be bought soon) perform much better than my old core2duo box even in gpu vitrualization?

I recently tried to get virgl working and couldn't even get the vm to start. Either virgl doesn't like nvidia, or I'm doing it wrong. Regardless, my understanding is that windows virgl support is experimental at best.
