i have just installed the sims 2 in my pc, and i found out that S3 Graphics ProSavageDDR is not compatible with the game. can i just update my driver so that i can play the game or is it necessary to change the driver? if i need to update the driver, what site can you recommend me? i saw one in the other thread the site but it's not working already. if i need to change my driver, how much will it cost me? thanks..
