Cpus i used were 7700x and 9700x Guest os is windows (linux didn't had most issues in the first place) No nested virt warning with wsl still persists (probably windows being wind= ows cause zen5 only guests don't have it) Pcie "slowdown" is gone using zen5 (no performance penalty on gpu) No issues with nvme drive passthrough (it would behave as broken hdd on zen4 having huge latency and increased temps for some reason - probably irq handling) --=20 You may reply to this email to add a comment.
