Thanks for posting your specs, this is why I ask - There is nothing wrong with the game in your case, it's definitely your video card.
Hate to break it to you but you have a revamped 9400 video card - those are pretty bad - and that's whats slowing you down. The memory bandwidth and processing cores are lacking. For 125ish you could get a card that would let you up the performance by quite a bit.
With only 8 cores its not really a "gaming" graphics card, more suited for videos and "work". It will never perform above "low" on dx10 + games.
I dont think it is my graphic card or soemthing else beauce if I face one direction my fps is 20+. But wheb I face the other it is 5-9. I am pretty sure tha it isn't my computer.
