Hi, Michael Thanks,
but my recent computer is a pentium Dual Core and the card is enough powerful. I have noticed a slowing down while job with the object of which you I send one screenshoot.
Bye
and good week end

Hi Nicola - there are a couple of things you can try.

One is to go to Options / View and set Mesh angle to a higher number, like 20 or 30. This will cause the shaded display of surfaces to use fewer polygons. This means they will look somewhat more rough on the screen (more jagged) but it helps to speed up the display since fewer polygons are being displayed.

The other thing on that same Options / View page is you can turn off hidden-line curves and edges, those can also slow things down a bit.

You might want to only loosen these settings when you are working on the full scene, and then switch back to the defaults when working on a smaller set of objects, because both a smoother display and the hidden-line edges are kind of useful to have on if possible.
