Help with strange appearence of model

I’m trying to complete a tutorial of a duck. After a while this happened. Does anyone know why it looks like this? It looks fine on other computers. So weird.

Hello - it’s hard to say without the file, but it looks like bad edges, or a video driver problem - can you please run the SystemInfo command in Rhino and copy/paste the results here, and post the model as well, just in case.

Could it be the graphic card drivers? They are updated to the newest drivers.

Your video driver is 6 years old, that would be your problem there.

Thank you so much

Well I don’t know if it’s even going to be possible to update that to a level where it’s going to work, but that would certainly seem to be the issue.
