Hello!
I formated my computer couple of days ago,
I'm running Windows 7 Enterprise x64 (I had Ultimate x64 before format)

The game worked perfect before I formated, I have no idea what have changed..

I tried to disable my antivirus, updated my audio and video drivers, updated directX
Nothing seems to help

I also tried to use the lowest resolution with the lowest settings.

Even if the fps shows 60-100, the game still laggs, It's like freezing for half a sec and then goes on.

I'm really lost here, Would appreciate your help!
