I've checked out previous topics, but I was hoping to get more help. Currently, I was running a video game from 1998.. so it is not by any means a demanding game as my 2000 cpu had 1gb of ram and ran the game fine. My MBP has been running it perfectly, until recently, I've been getting a lot of lag. Could someone help me out? I have a MBP from Summer '08. Thanks.
