Hello friends, i have counter strike source running on BootCamp in a Macbook Pro 2.5 with 3GB and 512 video, but all i got in stress test is 120 fps. I disabled vertical sync of nvidia. I know the only way i can make windows recognize 4GB is run on 64-bit windows, otherwise only 3GB will be recognized, but maybe someone could help me to get better frame rates in this game. Thanksss anyway!!!
