I installed 2 games on my Mac laptop story to play out of my house (the demos enough for me to do this)
So these famous games: "UT2004" and "Call of Duty", both greedy enough resources.
When I run UT2004, we will say that it is playable ... although some latent cases where the action (by which I mean when different players pulling in my visual field, it seeks more resources than when I'm alone in a corner)
However, with Call of Duty is a horror ... impossible to aim and evolve in the map so the latencies are important.
The graphic details of the 2 games are at the lowest course.
Considering that my Mac is a fairly recent, I have trouble believing that he has not enough power to run the game properly.
So if one of you not what drivers / drivers install in order to enjoy games, I thank in advance
