Got it today, the Colonies version is definitley the one, although the cutscenes are rather laggy, 8fps during the cutscenes, but 50-70fps whilst playing the game...
Cutscenes are perfect on an Nvidia card its your ATI drivers I'm affraidtry turning down AA to X4
What's your monitor resolution ???? as I can get very smooth cutscenes with a lowly GTX260-216 or even an 8600GTS !!!!Typed it in google and Nvidia users are having problems too.
Edit: Found the problem, cutscenes appear to hate my monitor resolution.
Make sure the game is running at the correct refresh rate as in the menus you will see it well hidden but it changes the refresh rate based on your resolution until you manually override it. Change it to 59 as it most probably gone to 60 or 59.9 should make a difference.1920 x 1080, it's just the cutscenes so i'm not fussed with it. I just found it odd that i can play games like Crysis, Far Cry 2 etc on the highest detail and i get 8fps on cutscenes in this game, yet i can still play it with 50-70fps when the cutscenes are gone.
