Hi, I am having some problem recently with my mbp. I have the 330m 15" version. I did a clean install when lion came out. My system has 8 gigs of ram and SSD as boot drive and 640GB storage drive (disk drive mod). Never had any major problem until recently. When ever I try to play starcraft 2, my system would lag down to crawl few minutes into it. I have plenty of free ram, free space on all harddrives and I never had this issue before. I tried restarting my computer with most of the items turned off and the problem still occurs. I am guessing the system is running out of vram but I really don't know why this didn't happen before. Any idea on how to debug or fix the problem? Thanks in advance.
