Hey guys,
I received my new iMac yesterday: 3,4Ghz i7, 4GB ram, 6970M 2GB. I installed Windows 7 Home Premium (64-bit) yesterday with bootcamp, which is working fine. I installed some windows games like Dragon Age 2, Crysis 2, Assassins Creed Brotherhood and GTA4 which all run fine on the highest settings, except for GTA4.
The game starts up fine and runs without lag, untill I start driving a car and start making turns. With turns I mean driving left or right. When I make a turn the game freezes for a second and then continues, this happens every time I make a turn.
The auto graphics configuration in-game sets the graphics to high on the native resolution. So I figured well let's try setting the graphics a bit lower, but it didn't make a difference, so I put them on the lowest possible. Still the same problem, lag when I drive left or right.
I looked up drivers for the AMD Radeon 6970M and downloaded and installed the Catalyst control center (http://support.amd.com/us/gpudownload/windows/Pages/radeonmob_win7-64.aspx#2) which installed the latest driver for the 6970M. But still no difference.
Has anyone ever heard about this problem? I can't seem to find it anywhere. Any suggestions how I can fix this, could it be a ram problem? (though I doubt that).
Let me know what you think
