I was running fusion 12 with Catalina and windows 10 2004 update with normal performance. Also Ubuntu 20.10 with good performance. Just updated to Big Sur. Ubuntu performance is inconsistent (snap updates take forever now). Windows 10 is so slow it is almost unusable. I tried re-install of tools. No change. I moved network to bridge mode. No improvement. I run with 4 vcpus and they are almost always running at 100%. My MacBook Pro has 4 cpus and shows 50% busy in the virtual machine almost all the time.
I have read the fusion 12 release notes for ideas, but nothing seems to help.
I NEED HELP!!!! PLEASE!
