V-Ray freezes my computer

[arail]

My computer freezes when I shut down Rhino / V-Ray. I'm confident that it's V-Ray because if I work in Rhino without using V-Ray, shutting down Rhino doesn't freeze the computer.
Any thoughts as to what I should do? Force quitting my computer is a drag.

Did you install the latest display driver?

Hello,
Could you please send an email to support@chaosgroup.com with detailed info about your system spec, Rhino and V-Ray versions, any other 3rd-party plugins you have in Rhino, and as Micha mentioned, whether you have the latest GPU drivers or not.

Kind regards,
Peter
