kvm is slower than virtual box.
 
Yep in title. Have a kvm windows 10 box, and a virtual box same specs, but kvm, supposedly good for gaming, is slower. I havent launched a game in kvm, but wifi and os are already slower than vb. How do i fix it?all virtualzation settings are on in bios.


Host: ubuntu 16.04

Doesn't it want two GPUs? One low end one for general display and then the big one used by the guest.

I installed kvm the gui way. Where, and how would i edit this, also I somewhat have 2 gpus on my host. Coffee lake graphics passing passing my p106 to host via prime rendering. Do i need a 2nd p106 to do this safely/ no ridk of bricking host? I tried bioshock 2 remastered, and its somewhat strange.

Windows in kvm uses "basic display adapter driver" so the gpu isnt near even fully used. (20% max) screen flashes in the kvm with game running. Since the gpu is simi-passedthrough, is there a way to make windows think its a 1060 without the driver or at least a high intel gpu controller so it'll use more of the p106? If itll see theres more power to use, id be perfect.
