Prince of Persia Sands of Time Trilogy

OK, so, here's the thing: I installed the Prince of Persia: Sands of Time Trilogy (Sands of Time, Warrior Within, Two Thrones) on Vista, and it worked perfectly. I upgraded wo Windows 7 Ultimate, and I am experiencing choppy gameplay, frame skips, etc...Any hel on this would be greatly appreciated.

For the Sands of Time game, go into the compatibility tab under the shortcut "properties", check these boxes: Run As Admin, Disable Visual Themes, and XP Service Pack 2. The game worked fairly well for me.
