Core i7 running on only 4 threads?

[Benedetta Candid]

When I check in task manager under performance tab (or any other CPU utility for that matter) I'm only seeing every other thread working. This is while running FSX or whatever. Is this normal? P6T Deluxe motherboard all cores enabled and hyper threading enabled.

Do any programs actually use 8 threads?

If a program only runs on two cores w/o HT (vast majority do), is that = 2 threads?

[Benedetta Candid]

To answer your questions; maybe 2 and yes. A little research answers the first question; a little common sense seems to answer the second. An answer to a question is nearly always a little quicker than a question to a question. But thanks for the questions, they questioned my question and answered my question all at the same time! If you have any more questions just let me know. I'm here and happy to question them.

FSX does not use HT. And although it uses multiple cores (with the patch), it is still effectively limited to 2 main cores and most importantly clock speed.
