Rhino 6 Display Refresh Issues

I have just installed Rhino 6 and the display won’t refresh automatically unless I click on the screen.

I am using Parallels Desktop for Window 7 on a Macbook pro 15".

Any help will be much appreciated. Thanks.


Parallels is not officially supported…

You’ll probably find that the output of Help > System Information gives you some very low OpenGL version (do paste here so we can check). Recommended is a setup with OpenGL 4.1 or better .

I can see my OpenGL is quite old. Does this mean I can resolve only if I have a setup with OpenGL 4.1?

Yep, that’s more than 7 years old… I don’t know if Parallels allows you to update the Nvidia drivers…
