New user - Problem with graphics on curved sufaces

Hi there!
I’m new to rhinoceros , i just installed the software and starting to learn , and i have some problems with the graphics. When i draw any object with curved surfaces , the graphics make strange sthings:

Maybe its something easy to solve but i really don’t know how to fix it!
Thank you!

Check your video drivers if they are up to date.

Please run the Rhino V6 SystemInfo command and post the results.
This will give us a good overview of what resources Rhino sees, and may allow us to make specific recommendations.

I think updating your graphic card drivers might help.

Hello - the display driver is 6 years old - if there is an newer one available from the Intel website, please install that and see if it helps - it may be that the video support on that system is simply not very good.


Hey , while i’m trying to update the graphics software , i have to say that i can run Solidworks and Autodesk Maya perfectly , and i don’t have any kind of graphics problem with them.
Is it possible to have lower resolution or something on rhino?
Thank you

Hi -

There are no settings that would make something like what you are seeing on your screen go away, no. That requires updated GPU drivers.
