I found that a few of my games will only work with Hyperthreading disabled. If I do that, will it have much of a performance hit on my other programs and games?

More about : worth hyperthreading enabled

in games that doens't support HT...the disabled P4 can output more raw power...
but when it comes to application which would benitfit from duo CPU...(PS7, Preimere...)
then the HT will help it greatly...(haven't u seen the demo of HT?

DON'T Disable HT in the BIOS. If a you want a certain program not to use HT then while the program is running press Alt+Ctrl+Del to bring up Task Manager. Under the Processes tab right click on the program and select Set Affinity. Only check the box next to CPU0. Now that program won't use HT.

That's a great sounding solution, where did you find it?

You need a multiprocessor kernel to see that affinity thing, but yes, it's there.

Multiprocessor-enabled OSs usually check for # of CPUs when installing, and install the appropriate kernel - single-processor or multi-processor kernel.

Wow a new name for pop corn Multiprocesser kernel. I like it. As good as Cyrix chips. Taste good too.

I'm talking about Windows XP but I'm sure Win2k also has this feature.
