AutoCAD Civil 3D

Please go to Option -> System tab -> and under Layout Regen options select Cache model tab and all layouts (Apply and OK).

In some cases this can be drawing specific, please check that as well.

also LAYOUTGENCTL 2, correct?  Cuts me down to a 6-7 second lag before cursor responds again.  Little irritating but useable and hopefully when I get our RAM issue resolved it will speed up a little. 

Still curious about some BIOS settings so I guess I'll start another thread and hopefully someone can jump in.

Thnx

Yes, keep the LAYOUTREGENCTL set as 2....

Did this solve the problem? If not, did you find a solution?

With the latest updates from AutoDesk for Civil 3D 2012 and the ATI FirePro AutoCAD Maximum Driver our machines are useable, not mind blowing fast but a whole lot better.  All computers and our templates are set to cache model and layouts for regeneration, it helps immensly once all the tabs are cached.
