It has happened several times now…on different models. When using clipping plane either Rhino freezes or even worse the computer. When I pick up the model in Rhino 6 and repeats the same commands, everything is OK??? Some of my models are size 200-500 MB. But newer the less, no problems in Rhino 6. This happens in Rhino 7. Does Rhino 7 require more memory? As for now, I just have to continue working with R6 
Hei Dag -
Could you please run the Rhino SystemInfo command in Rhino 7 and copy-paste the result here?
Mvh,

Hei Dag -
Note that the minimum recommended VRAM is 4GB.
That said, I would start with updating the drivers for that GPU. In terms of GPU drivers, 2019 is ancient. When you open the Rhino Notifications panel, there should be links guiding you to the Intel page.
