i have a sony vaio, now supposedly this computer is supposed to tear threw any game. i bought empire total war, i was so excited to play it, install and go to play and every part of the game has this tearing effect, making triangles and i can barely see my units, its horrible. i have ATI radeon hd 4650, intel core duo 2.53GHZ and 1GB of vram dedicated. i really dont know much about what all that means. i just want some help on how to fix this problem so i can enjoy this game. any help will be appreciated.
