Hi,
Does anyone experience extreme slowdowns during gameplay and when playing any of the soundtracks?
The menu itself is quick and snappy, including the menu sound effects. However, when I start a game the framerate is about 10fps with heavy stuttering sound.
The same stuttering sound happens when playing the soundtracks.

To answer my own question:
Disable vsync in the game options screen.

Make sure you're in the toplevel menu (where you can choose between Aladdin and Lion King), otherwise you won't see the option.
