Dual Processor Configuration for Winodws

Anonymous

Hi All,
I work with the U.S. Corps of Engineers in the Tech Support Branch. We have a user using ArchiCAD 9.0 build 2045 His system has 3 GIG of memory... 2- 3.6 GHZ processors.. it seems when he generates fly-thrus. The CPU usage is only around 25% on one CPU and less on the second.. If we move the process priority to above normal, the first CPU goes to 100% and the second is less than 20%. I would think this would load balance better. This is running on a Windows XP SP2. Any thoughts would be greatly appricated... Thanks, Dave.

Archicad is not optimized for multiple processors.

Is there any way to speed it up?

Sounds like you've already got a fast machine with a boatload of RAM. That's about it.

We're doing fly-throughts on Cinema 4D, which can use our 30 Mac G5 machines as a render farm. Single machines took too long for anything higher than screen resolution or more than several seconds long.

As far as I know, the only time ArchiCAD uses the two processors is when you are using the LightWorks rendering engine.
Otherwise that's about the fastest you can go.

I don't know if using fast SCSI drives would make any significant, perceiveable difference. It might.
