OK we have new graphics cards. ATI Firepro V58000
And we are both experiencing blocky previews whilst zooming in on a drawing. (Sometimes it dissapears completely and you have to refresh to get the drawing back)
I'm assuming it's to speed things up whilst zooming in and out of your drawing, saving resources until you stop then loading the full graphics?
As you can see from below, looks really horrible. I would rather just see clean graphics throughout the zoom / pan.
Can anyone shed any light on this?
(Seems to happen more on heavy assemblies)
