On my normal windows 11 computer, VCV correctly senses the DPI, and does what apples calls “retina mode”. that is to say things come out “normal” sized, not tinny.
On the same machine when I run Ubuntu Linux under VMWare Player, everything is tinny, including VCV Rack.
in my experience it is a issue related to the drivers, it is hard to fix on virtual machines, try to find a way to install close source drivers if needed
