When coming into close contact with the enemy, staring down my sight, and firing at the enemy, either when i start shooting or the enemy starts shooting full Auto, the game goes from 40-55 FPS, down to a stutter for every shot, which results in one always losing the gun fight. Not sure what the cause is, but it seriously needs a fix. A gun firing should not freeze up and stutter the game, as it becomes un-playable to go into a CQB situation.
