I have a MacBook 13.3 2.4 GHZ with Intel GMA X3100. Games that I was able to run are GTA VS, GTA SA (with laggs), L4D (with laggs), CSS, CS 1.6, CSCZ, NFSUC (with lowest settings, about 2 % lagging), NFS PS (running better than on 4gb sony vaio (no laggs)), NFSUG2 (little laggy), NFSMW-BE (1% laggs), COD2, COD4 SP and MP with almost no laggs on 800X600 and some low settings, tried on 1280X800 was lagging a bit, but still was ok. Far Cry (hardcore lagging), SimCity (2% Laggs), SIMS 2 (no laggs), SIMS 3 (little laggy), BF 2142, BF 1942, NFS Carbon (UnOfficial Cider). So far, there's only one game that didn't work, is CODMW2 (cider). Trying to get it work somehow. Mafia- The Game, Age of Empires III, Quake III, Quake IV (laggs), OutRun 2006, Splinter Cell, NBA Live, Command and Conquer III Red Alert, Halo. There are more to it to add, but I gotta remember, so yeah. This is not a joke.
