About switching the display of SubD

I am just starting to get acquainted with Rhino7 and came across the fact that I can not switch smooth and flat display in the viewport.
I’ve tried using both the Tab and SubD Tools command.

Hi @ave4ra
Run the SystemInfo command in Rhino and paste the results here. It could very well be graphics card driver related, so if the are old, you might want to update.
