Looking glass Windows 10 guest vm ( kvm ) runs sluggish


I have a RX 6600 connected via 16 PCIe 4.0 lanes passed through to the Windows 10 guest but the performance is choppy on games that should run flawlessly at 1080p.

Anybody knows how to improve performance in a kvm / virtmanager vm?

I installed everything from the looking glass site.

Are there any optimizations?

I’ve had similar problems and dropped looking glass entirely. It’s not a perfect solution and the current, recommended release is pretty old. I think it’s just a looking glass problem.

Many, post your client and host logs, along with your full system specifications.

No it isn’t.

Very likely not, if you had asked for some assistance you would likey have had your issue solved.
