when i m playing BF3 my i7 950 usage is about 40%. when i turn hyperthreading off my cpu usage is 80%.if there is any other game or app that when i have hyperthreading on use more than 50% of my cpu, when i turn hyperthreading off what ll be the usage?

It is good that cpu usage is low, you want more gpu usage. Do you only play battlefield 3? Hyperthreading is not needed for games, but in multi threaded applications such as video editing programs can take great advantage of those extra threads.

yes only BF3 but at the same time i run oovoo video call ,internet browser and other apps so i need Hyperthreading :)

Hyperthreading adds core count to windows task manager. TM simply divides the cpu usage across all cores by how many cores there are. Sometimes windows loads full cores before HT cores so the HT cores are 0% usage.

Calculations: cpu 80%, HT core 0%. add together, 80%, divide by threads (2) = 40%

average cpu usage, 40% because windows isn't using the HT core, but is calculating it.
