Proxmox cursor delay in (some) WMs'

[cheeki-breeki]

i’m having strong cursor delay in some VM’s.
it’s not IO delay, as there is none in some.
this is happening even if device is passed through.
currently testing.
noticed, when in a game and i move cursor rapidly fps drops to half.
haven’t found anything from searching, so even search strings appreciated.
will update with requested info.

Hi!

This is a well known problem, the virtual USB port couses the "interrupts problem".

Solution:
-You need a PCI-E USB Card that also passed-through (the entire card, not just the ports) to the VM, then you connect the mouse/keyboard to this card.
