If you're getting into the competitive gaming scene you'll need to upgrade as your PC is near the minimum requirements to run BF3 regarding your GPU and CPU.  In fact your CPU may be bottlenecking the game contributing to the problem. Was the game ever able to play without this problem or has it been present since the beginning of playing BF3?
