...them afterwards. Proper context switching is key to effective resource sharing. As there are times when I notice some of my VM's seem to stutter, could the missing XSAVES be the reason/cause of that? I'm trying to figure out the value of fixing this vs. risk of messing with it given things...

...GPU (with 512 memory) and it runs slightly better on this but still pretty poor. If I try to play a youtube video on it for example it will stutter and lag. Even with youtube video all the way down to 360p it still struggles to play it smoothly. The VM cpu is showing only 40 to 50% max when...

...between the two links over and over, and every time it does that it causes the vmbr0 interface to go down and up and it creates a noticeable stutter effect for example when connected via ssh or rdp in a vm inside the pve or the pve itself. Disabling the ethernet ports on the switch fixed the...

Not using all cores often works better because you are never at 100% and therefore CPU usage from Proxmox and virtualization overhead (network, disk, etc.) or other VMs then don't cause stutter.

I'm seeing the same 4 cores at 80% but it works without any stutter/lags (at 1280x1024) with Ryzen CPU with 8 cores or more. You only have 4 cores, so the software rendering of SPICE (and other virtualization overhead) is simply asking too much from your CPU. I'm almost sure that SPICE does...

...isn't great. Watching a YouTube video stresses all 4 virtual cores to about 80%. The mouse pointer is laggy, graphics and audio also stutter. My hardware is a Dell Optiplex 9020 with 16GB RAM and 500GB HDD. 4 x Intel(R) Core(TM) i5-4590S CPU @ 3.00GHz (1 Socket) I have activated IOMMU and...

Give the VM less cores and less ram because making sure that the VM does not use 100% of anything make everything smoother; go for 50% at most or use bare-metal instead of Proxmox. Also search the forum for stutter (and similar terms) and read the advise people give.

...Can't successfully recreate and don't know if it's worth doing but thought it was kind of interesting I've almost completely eliminated the stutter, but it's not gone. If you listen to a youtube video you will very periodically hear the audio glitch very slightly. I'm also seeing correlating...

...the qemu string sent hpet=off as a parameter. That appears to possibly be the biggest impacting piece of the config. I'm still getting slight stutter/mouse jitter though. I need this passthrough VDI to perform like bare metal. Or at least well enough to convince a non-savvy user as such. I'm...

After reverting the changes between my OP and now I am seeing more exaggerated and frequent stutter than previously.

I think I ran into a related issue with my two NVMe drives back with the 6.1 opt-in kernel, see my post here. You could try and compare the device links in /dev/disk/by-id/ (i.e. not only in /dev/ !) between 5.15 and 6.2, because at least for me they have changed since 5.19 (i.e. due to the bug...

I'm running 'Linux 6.2.9-1-pve #1 SMP PREEMPT_DYNAMIC PVE 6.2.9-1 (2023-03-31T10:48Z)' and have been having issues with my HBA recognising sata ports five to ten. So started using 6.2 but still no luck thusfar. I read that my new ASM1062+JMB585 based BHA required kernel 6.x for the kernel...

...for. If you want a smoothly running VM then make sure that it can never use all of the performance (of any subsystem), otherwise it might stutter or have interference from other VMs or background processing of Proxmox. But this also prevents you from getting maximum performance...

...well as Steam Remote Play (with NVFBC). While the framerate is quite "jumpy", I have unreasonably high frame time variances, which feels like stutters.
