------- Additional Comments From l_bratch@yahoo.co.uk 2007-24-06 17:05 ------- I didn't actually have much of a slowdown or freezing issue, it just appeared that way due to the unsmooth mouse movement.
Although the native DLLs fix the smoothness, it's more playable with the builtins as the mouse constraint issue doesn't appear.
Do you really think CPU speed is causing the issue for you? I'm running a Core 2 Duo E6700, which in fairness is a fast CPU.
