i just bought this little magnificent macbook, 2.4 gh, 2g ram and the 3100 graphic card that comes with it. Well, the alien vs predator 2 game refuses to start because either I have to upgrade mac os x or the graphic card. AVP2 is 5 years old, come on. Games like ut2004 or heroes V (2006) run like they had the devil chasing them. Here is the message : The currently installed OpenGL drivers (Intel GMA X3100 OpenGL Engine 1.2 APPLE-1.5.26) do not support the 'GL_ATI_texture_env_combine3' extension. This is a required extension for this game. Please make sure you have the latest version of Mac OS X and the latest drivers from your video card manufacturer. anything i could do ? or is it just that the game developpers for mac were on crack ?
