So, I've been trying to turn off hyperthreading on my HP DV7 notebook, which is impossible because the BIOS setting isn't there (thanks HP!). I tried turning the number of processor cores used in MSConfig to 4 but instead it disabled 2 of my cores and left hyperthreading on. But when I played Starcraft 2 which only 2 cores on, I got a 100% increase in framerate... yes, a 100% increase. I was playing the mission Outbreak and got 10-20 FPS on High Settings with all cores on, but when I played it with only 2 cores on, I got 30-50 fps. I suppose this has something to do with the i7's turbo boost feature (which is now really cool in my opinion).
I think this is a really cool discovery and makes quad core processors equipped with turbo-boost much better than I previously though for applications which don't support utilizing all threads.
.... first off its pretty sad you cant run sc2 at 50 fps in the first place, Inless you have an onboard video card. Which might make more sense why you see an increase when shutting down cores.
... Quad Core notebook huh.... sounds like you prolly have to keep the sucker plugged into a wall.
1: It's on high settings, I said that.. Not low or medium, My laptop has no issues running it,
My laptop has a HD Mobility 5650, so it can run it pretty well.
2. Yes I do use it only plugged in for games, when on battery I have it on uber power-save mode for when I use it in class for notes.
So, next time, don't criticize my computer without reading everything that I said, and next time bring something useful to the conversation.
Sorry if I sound rude, but you insult the quality of my tech even though I specifically stated "HIGH" settings and you don't even bother to address the topic at hand.

The only thing you are able to do in MSConfig is setting the amounts of cores used when the comp is booting and i really dont see how you disabled anything else there.

What I was getting at is it sounds like your computer is doing something wrong.
And like the previous post. Im pretty sure you cant turn off cores in MS-Config.
I retested it. I conclude that the difference in performance between 2 cores disabled and 0 cores disabled isn't a great as I initially thought, though it was still noticeable. 5-10 fps on the map Outbreak under a range of heavy to light load. The difference was lowest between the 2 at a light load (where the frame difference was negligible) and greatest at a high load (lots of units, not even necessarily on screen but doing actions like raping my base).
Maybe you can't "turn off" cores, but you can specify how many cores that windows uses. When I put in 4 cores under msconfig (in the boot options), after I reboot, task managed shows 4 logical cores instead of 8 and CPU-Z shows 2 cores/4threads instead of 4/8. Also, when I disabled 2 cores through msconfig, cpu-z showed higher base clock speeds on my other two cores, which is to be expected due to turbo boost and was the whole point I was getting at... the possibility of disabling cores to effectively utilize the power of turbo-boost on single/double threaded applications. (assuming turbo boost is not fully effective when the core is enabled due to background threads / processes)
This has nothing to do with hyperthreading as I can't turn the damn thing off thanks to the limited BIOS options that HP decided to install on their laptops.
And Soulcarverr, then how is it wrong that my notebook can't run high at 50 fps. Is there something wrong there? Do I need to spend 2000 dollars and a stupid school laptop for it to be considered decent by you? My laptop isn't doing anything wrong as far as I can tell. The only thing that is messed up on my computer is Catalyst Control Center, which I uninstalled because it was just causing problems.
lol man I wasnt insulting your damn laptop. relax. Did you see the part where i said "inless your running onboard video.... which your more then likely are.... since its a notepad thingamabobber.

This whole thing sounds strange... i know that hyperthreading can result in a loss of performance in certain games.

I have a ATI Radeon Mobility HD 5650. I thought I said that but I might not've. Sorry, I get defensive sometimes. :(
Edit: I said that I had a HD Mobility 5650, but not ATI or anything so my bad. I apologize.
