According to Steve Bell, Vue does not take advantage of Hyperthreading. I recently purchased a new Sony Vaio P4 2.5GHZ and it seems that Vue runs SLOWER than on my Athlon 900mHz. It looks like the computer is using only 50 percent of the processor to render. So, you can turn this hyperthreading off? Someone PLEASE tell me how, since all I can get from Sony is "Hyperthreading is a wonderful new performance enhancer that increases...blah blah balh." Do I do it through the bios? Is there a way using XP (I really DON'T like XP) to turn it off? I'd much rather have ONE processor chewing on this program at 2.5 Ghz than having two VIRTUAL processors at 1.25 Ghz... -Dr. Nash
