Henrik,
I found the information, but here are some other recommendations that I'll make first:
1. Ensure that you defrag your harddrive often, especially if you do a lot of work such as capturing video, deleting video files etc. Before you defrg though clear out any files you don't need by following these steps"
a. Go to All Programs/Accessories/System Tools/Disk Cleanup and use it to delete your internet files etc.
b. Go to Explorer and go to Documents and Settings/Your_UserName/Local Settings/Temp and delete any files there.

If you do not see this folder click Tools on the menu bar, Folder Options... select the View tab and select the radio button for Hidden files and folders to Show hidden files and folders and select OK.
NOTE: There will be a file or two that looks something like ~DF771.tmp that has the current date. This is a system file that you can't delete so don't worry about it. Also the letters and numbers will be different than what I showed; it changes each day.
c. Go to Windows/Temp and delete any files there. There will be one or two files there that end with .TMP that you can't delete either (again a temporary system file) but they're only 1KB big.
d. Go to C:/Temp if you have one and delete any files you have there.
e. Now defrag your hard drive.
2. It's a good idea to always leave at least 15% of your harddrive free. If you get below that Windows will complain when you defrag. Plus you probably will notice a performance hit.
3. Ensure that your Virtual Memory setting is 1.5 times your memory. I think Ulead actually recommends 2 times your memory. Look in the User Manual. To set your virtual memory press WIN+Break; click on the Advanced tab; click Settings under Performance; click the Advanced tab; go to Virtual Memory and click Change; select the radio button for Custom Size and make your Initial Size and Maximum Size the same then click Set. So if you use Ulead's recommendation that would be 2000. Make sure that select Set before you select OK. If I remember correctly you'll be told that you'll need to reboot for the settings to take affect.
Hardcore Gamers also look to tweak their systems for max performance so the site for how to create a Hardware Profile is
http://www.technobabble.com.au/technoba ... aming1.htm. If you do a Google search on Hardware Profile for Gaming Machine I'm sure you'll find other resources as well. Hardware that you may consider disabling under your new hardware profile would be your network card(s) (which means no internet), modem, printer, and extra CD drive (but not your DVD writer).
If you do decide to create a hardware profile, once you've rebooted into that profile and disable your selected hardware devices you may also want to think about keeping some software programs from starting up. To do so, press WIN+R, type msconfig and select OK, go to the Startup Tab and here you'll see a list of program's that you may want to not have startup such as iTunesHelper, qttask, realsched, your antivirus software and your firewall (which you won't need since you're not connected to the internet), etc.
Finally, you can tweak your Display to use less resources by right-clicking on your desktop, select the Appearance tab, and change it to Windows Classic Style; then go to the Desktop tab and change background to None and press OK.
BTW, I personally don't use a hardware profile because with my system I'm getting about a 1 to 1 render time.
Hope this helps,
Ron G.
