I've been playing a little bit with HD5870 under LN2, and after a certain point, no matter what clocks, volts or temps I would use on the card, it would freeze at this frame. I tried lower CPu clock, so that is not it. Any issues known with the latest 9.12 Hotfix and Windows 7 32bits and 2k3? After I have submitted one score, I have seen that there is a newer 2k3 hotfix available on FM. Did that solve some compatibility issues with Windows 7 by any chance?
