(Solved) Keyboard RGB stutter

My keyboard and mouse lighting effects have a stuttering issue when passed through to my Windows VM (ie. it normally is a smooth 60hz, now it's 30~). I don't have a problem when I'm running Windows barebones. Sometimes my mouse also feels like it has difficulty tracking for a split second, but that may just be because I'm bad.

Are you passing through the USB controller they're attached to or just checking off the keyboard / mouse when you edit the VM template?

Just checking off the KB / using the Hotplug USB plugin. I don't have a usb card yet but I'm planning on one for my pile of usb devices.

Could be it.  There's latency, overhead, etc when KVM is basically emulating a usb controller

Ahh I see. I thought it was more straightforward than that. Would it help to have USB 3.0 selected in the configurator for better speeds on USB disks? Probably also why my USB DAC/amp crackles as well. Thanks for the tips.

Swapping to the USB 3.0 qemu XHCI emulated drivers fixed the issue for the KB. Will see if the audio is fixed later
