Im listing any games that are playable or not playable in which settings and through how, my aluminum macbook is the 2.4 Ghz model with 4GB RAM .4 ghz doesnt make such a difference, so onto the games. WoW(world of warcraft) : Settings : Highest on any setting possible. Graphics: 9/10 Lags/Delays : None. The game runs smoothly on any area even in populated areas and got 30fps lowest in Any City. Counter Strike Source(through Crossover): Settings: Highest settings possible with bloom effect. Graphics :10/10 Lags/Delay: 8/10 using cross over it lags a little. Age of Empires 3: Settings : the settings were set to high with no AA on 1280x 800 resolution Graphics : 8/10 Lags/Delay: None. Unless settings were set higher than high. Company of Heroes: Dont even try it on the mac os. use Xp or Vista to play it. Call of Duty 4: Settings : Most settings were set to medium except texture put on high and other settings.i also put the resolution to 1024 to not get lag on multiplayer. Lags/Delays: i would recommend playing this on vista as the DirectX10 will help it to put settings on high and still play smooth. *Note if only played on single player settings could be set to play on high with 1024 and would not get any delay. Later on i will post up more games, if anyone needs to find out about a game reply on this thread and i will try to get it as fast as i could. Note****** found out something interesting, in Windows Xp your Vram gets increased to 512, so if you have alot of ram (4 gb or higher than 2 gb) than you should think about getting windows xp for gaming .
