Hello,
I'm using spice in virt-manager, but it's slow in video. I've been
using spice in my NUC, with the same configuration, that's fluently. The
biggest difference between my NUC and desktop is hardware is different. NUC
is using a integrated graphics while desktop using a RTI RX 550/560(I don't
remember).
Is there any suggestions to make the VM video performance faster?
Hardware of my desktop:
$ lspci | grep VGA
09:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
Baffin [Radeon RX 550 640SP / RX 560/560X] (rev ff)
$ lscpu | grep 'Model name'
Model name: AMD Ryzen 7 5800X 8-Core Processor
