[Stutter on Windows when soft load on host]

but now i notice I have the sttuters only when high network usage, if for example I run iperf3 between host and guest I got 1.27gbps when I should got 10gbps and the VM is completely unusable meanwhile the test is running

 

 

 

 

I have this exact same issue, any luck with fixing this?

[hiptoss VM issues (split from Windows issues with unRAID)]

I’m doubtful this will ever get sorted I can’t understand why unraid staff can’t type up how to downgrade properly from 6.9.0 beta 25 to 6.8.3 again without losing cache drives the tiny little info on the pre release you get doesn’t make any sense to me

 

I was pulling my hair out for hours a couple weeks ago getting this all working. First AMD build in a loooooong time on a Ryzen 3700x + Asrock B550m Steel legend. After working out that I needed to move to 6.9 beta 25 for the internal NIC, I obviously found my self in the same position. Not sure where I found this from, but those commandline arguments are key to a successful win10 VM using host past thru. My build has been solid since working this out! Hope it helps!
