If it was ‘top’ from the Linux host, the arithmetics should be 20% ( out of 1200% in your case). So it has to go through a normalisation process. After that you got 1.7% CPU utilisation for your MacOS VM. Not bad at all…
What a coincidence! My “rx560” with 4GB idle at between 25-30W as reported by MacOS Baffin driver. I had to patch the open-source monitor software to have the correct offset. Once done, wattage reporting goes very well and accurate.
I dug out my previous conversation with the dude [0]. Seems rx6600/xt still no luck. There could be quite a few of potential issues in wake up properly. In my case, I’m pretty sure GPU is the last hurdle I need to cross. But probably not worth the time to investigate further as we all know MacOS on AMD64 will be over around year 2028.
I’m running my “rx560” at 4K@60Hz RGB444 with “look a like 1440p” scaled resolution. Perfectly fine. A physical display really makes a VM pop and real…
Windows 10 VM hibernates and wakes up well for me with the same “rx560” gpu. Hibernation is a must-have for Windows. Because “reopen applications on startup” doesn’t exist for Windows at all…
I’m not sure what will be my Daily Desktop after 2028. Going Linux is one possibility. Buying a Mac mini with 7 angstrom is another possibility. Good that I don’t have to decide for now.
