I recently updated my ATI Radeon HD 2600 PRO driver to the latest one (I believe it is 9.2. And now my FPS is very low and the game is stuttering and just a plain mess. Does anyone know what the best version of driver for this card would be? I have heard that the newest is not always the best. I am running Windows Vista 32 bit. Any other info you need, please let me know.
