Also, my computer fan seems to have gotten louder since the Vista 64 install.

when was the last time your machine was wiped clean (formatted)? this can eradicate many defragmentation issues and poor performance created by registry clutter adn the like. I do mine once every year personally and professionally. I have always been extremely satisfied with the better performance of all my machines after doing this. It always returns "like new" system performance in my machines.

Havent done that. You re-formatt once a year? If I didnt have to re-install all of the software it would be worth it.

I do. the pertformance benefit is well worth it. I have not done it fully yet but you can create slipstreamed install disks of OS and any other software programs to install unattended. You click once and it installs everything for you without any user input. Laso you could create a disk image after you do this the very first time and then always have a disk image to install from which would also make it a less time consuming and painful process. I am positive this would fix your performace issues and allow you to see the true benefit of the 64 bit features. 8 Gig of Ram is crucial to it all though. we have done the 3 gig switch and actually i am the only one with a 64 bit machine so everyone else is still using the old machines with the 4 gig of ram and the 3 gig switch and they still crash all the time. we (i am in charge of technology and the like along with another guy) have tried and tried to get our leadership team to understand that while getting 20 or so new hig performance machines would be an expensive undertaking in these times of economic malaise, it a necessary evil. I mean we are paying for the new machines whether we have them or not by the shear un-efficiency of the old machines keeping our project budgets to the max with little to no profit. Might as well have the new machinesknow what I mean. Sorry I took a turn for the sopbox and needed to vent apparantly. =)

"I wouldn't expect a dual treaded Revit with in the next two releases. So probably not till 2012. It is true that Archicad is dual core capible, but it still takes archicad just as long to do things as it takes Revit. If you are using an OS that is 64 bit you NEED to have more than 4 gigs of ram. If you are just putting 4GB on it, then use XP x86 and turn on the three gig switch, you will get much better proformance out of that than you will from a 64 with 4. A 64 needs more than 4 gigs to run efficiently. 8 is probably pretty optimum, unless you can affords Crucials 4 gig stick that costs 12gigs for $1100. Running a 64 OS with 64 Revit will not get you these better results unless you have more than 4 gigs. As for the I7vs the Xeon...I dont have any benchmarks, but the Xeon completly out proformed the Phenonm from AMD, and the I7 has done the same thing to the xeon. The only thing I would wait for with the I7 would be motherboards that allow 8 or more gigs of DDR3, right now most of the boards are using DDR2, which is going to be gone soon making it hard to upgrade. If you get the I7 get DDR3 ram."

jmqrsq, I dont know if we have the same video cards, but I have a Nvidia Quadro FX1700 and since I have installed the 64 bit vista, the fan spins faster now and is louder.

I have the same vid card. the fx 1700 as well. I seriously think your previous windows install might have gotten "tangled" to some degree with the 64 bit vista version. Try to format and reinstall everything fresh. pending hardware failures I am sure you will have a much better experience.

Got the card fix. Incorrect driver was installed. I read somewhere that the render program does not use the on board video GPU. How do you utilize the card to its full potential? Is there a way to force Revit and Accurender to use it?

Well the video card doesnt actually help with the rendering process as far as I know. It only "renders" onscreen images for your viewing pleasure. The CPU(s" are what does all the heavy lifting in creating the actual render of the geometry. So I do not think its a natural ability of the GPU to help out with that other than showing it on your screen nicer/faster. Someone can correct me if I am wrong. J

I think its only free to Autodesk subscription holders. I know I had to download it from our subscription page. Maybe its changed since then though. Feel free to correct me....

Does anyone know if the mental ray engine within Revit 2009 utilize more than 4 cores? Because I would like to clarify: Revit modeling only utilizes (1) core but the rendering utilizes more than (1) core? We're trying to find a suitable machine set up for maximizing efficiency in modeling and rendering.
