Is it normal when control clicking single objects (ex. selecting/highlighting multiple windows one at a time with the ctrl click) for it to lag after each selectio? The lag only lasts for a split second, but if you are clicking fast enough you can be 2 or 3 or 4 objects ahead of the program, and have to wait for it to catch up.

It shouldnt be my laptop I am running it from I dont think anyways. I just got a new one with 6 gigs of ram and core i7 processor. The program is basically fresh installed, I havent messed with any of the advanced settings or anything like that because I have only have had it on the laptop less than a week.

*Much appreciatation to anyone who can help me*

How's the video card on the laptop?  usually laptop manufacturers don't advertise that feature, and include something relatively gimped while touting features such as the processors and the ram.  Just in my experience.. I've bought a dud or two in my time.   Back in 2002 I bought a laptop with a 2.8Ghz processor and 2 gigs of ram (!!!!)... and a 32 megabyte integrated video card that could hardly deal with youtube. I hate to be a pessimist, but Revit has very few success stories coming from laptop owners, from what I've seen on this board.

a few suggestions--You could work in Hidden Line views, employ crop regions or section boxes in your views if there's a vast site to render, make sure shadows are disabled, and extraneous views are closed, instead of open in the background.  I would turn off 3D acceleration.  Update graphics drivers too   If you're in Vista or win 7, you could disable Aero for a small boost in performance too.

The video card is an ATI Mobility Radeon HD 5650, do you think that is sufficient?

Thanks for the other suggestions, I'l try them out to see if it helps with the performance.

I have a Dell M65 and it worked well last 4 years without any problem, but it has an old NVidia Quadro FX 350M.

Now with REVIT 2011 it appear have incompatibility. It´s expensive, but a proper workstation runs better than any other notebook model .

I agree that a nice desktop is really needed to be efficient with revit, and there's no such thing as overkill for this application... revit will eat up all the processing you can throw at it.

This is your video card!  I'm not an expert, but seeing how it struggles a bit with high-end, benchmark games like Crysis, that's not a great omen... putting it on par with my home desktop card I purchased 3 years ago for $250.  At our office, we've retired all of our workstations with similar graphics cards, or sent them to be used by Autocad drafters and receptionists and the like. 

Your performance sounds about normal for your machine!  I'd try to limit the demands you place on it.
