Brian_MMC,
I was a Vista user.

I had to go BACK to XP, because no matter what (I even installed a new Graphics Card thinking that was going to help) AutoCAD Architecture was sooooooooooooooooooo slow!!! I couldnt draw!!

My best advice would to install XP!!

Best Move I have EVER made!!

Hopes this help!!

Thanks for all the info.

Do any of you know of a way to make A-Cad use more than 1 processor at a time? The affinity is set for all 4 of them but Cad maxes out one and then stalls out and starts eating up the memory and still just sits there. Any thing would be great.
Thanks in advance.

Check your Help files for information on the WHIPTHREAD variable.

You can also start having slow-downs and autocad-related problems if your hard drive hasn't been defragmented in a while. With 2009, I was having all kinds of problems. Autocad was actually just closing in the middle of me working on a something with no error messages and no warnings. What a nightmare!

Also, I realized that my video card driver was very outdated. Whether or not an outdated vidcard driver would slowdown autocad, I'm not sure. But It probably can't hurt to check and be up to date.

Then there's multitasking. Some drawing files can get pretty resource-intensive. And other programs running at the same time Autocad is running can create a big resource drain on things like system memory. If I ever work on really big drawing files I always close all the stuff running in the background I'm not needing or using. Things like Quicktime and adobe background programs. Even if it only frees up just a little bit of much-needed resources, it can make a big difference.

Another issue can be background spyware scans and/or virus-scans that have been either programmed to run at specific times and dates or are set, by default, to run during work hours. And sometimes these scans will take place on your computer while running in the system tray (just depending on the program) and it won't tell you it's even scanning anything until AFTER the scan is complete. Always good to check all your security software to make sure no scans are scheduled during work hours. I set all mine to like 3am or something.

Cad64 thanks for the tip on the Whipthread command. It is currently set to 1
"Regeneration multithreaded processing only; regeneration processing is distributed across two processors on a multiprocessor machine."
I will try the other options.

Thanks for the help.

would this apply to a multi core processor? i am running a Xeon 5150 2.66GHz (for whatever reason). I checked Intel and it is a Dual Core (available in quad but we're cheap).

Yes, it would. I've had this issue is quite a few computers now.

what variable would you recommend? its set currently to 1. I'll try 3 and see what happens.

Just keep an eye on it if you do. I used that setting once, hoping to use more than 1 of my 4 cores.
It took me months and several severe Autocad-crashes with a lot of work lost before i discovered it was the whipthread setting that caused it. Never again!
