Slow drag on rhino7 vs rhino6

Hello, upgraded to rhino7, but can’t work with old files (rhino6 not great performance, but usable) they lag a lot. Rhino7 any drag (gumball by hand) of curves have to wait for second to finish the action. Adding print screen with everything in file.

Try upgrading video drivers to see if V7 works better.
Also a System Information from V7 would be useful.

Here it is.

So updated drivers. This action drag took about 90 seconds. ctrl + z same time.

Rhino7

I’ve heard about people having problems with old V6 files when Vray is enabled (problems with old material’s paths).
Try disabling it to see if this is the case.
