I'm running MEP 2011 and Revit 2011. My pc has a quad Xeon process, 16 gig ram, Ati Firepro v7800 video card. I'm thinking it would be lightning fast working in files that are from 50 to 100 meg. Is there a setting in Autocad to get maximum speed out of it?
Are you working on files over a network or with lots of xref files on the network? Are you using a certified video driver?
What specifically is so slow about it?
Opening and saving?
Is the cursor sort of "sticky" as you move it?
Are there certain commands that respond slowly?
Does it behave the same if you use a different Windows profile (i.e.: log in as a different user, preferably one who has never logged on to that machine before)
Does it behave the same if you disconnect all network connections (including unplugging the network cable and kill all wifi connections)
in my case, Inventor is much faster than Acad. i concluded that if you want to work at optimal way with serious engineering software install only one such on you PC.
also i think Revit and Acad should be avoided to isntall on same workstation. all these dll fiels and registry modifications that each apps do create real mess on you working station.
It is slow when zooming in and out, during regens. I have the files locally on my pc not on the server. No xrefs just equipment that has been loaded into the Revit file. I wasnt sure if there were some settings in options that I could change to make the programs use the power and performance of my pc. Im looking for faster results from MEP and Revit.
Make sure you are running the certified video driver for your card as recommended by Autodesk:
