Rhino Blackviewports

Hi, I’ve been working with Rhino for over a month now but over the past week my viewports freeze up and I can’t do anything in them but can still type in my command bar. I save my file pressing ‘control s’ and then my viewports keep become black and I can’t see anything. I then have to close my file and reopen it but the same thing keeps repeating.

this is my settings:

Hi -

I’m afraid it will be very limited what you can do in Rhino with that GPU. We recommend a minimum of 4GB of VRAM - Rhino - System Requirements
You can try disabling GPU Tessellation on the Rhino Options -> View -> OpenGL page and restarting Rhino. If that doesn’t do much, try throttling back the “Level” slider on that page - one notch to the left at a time and restart Rhino in between tries.
