Joe, I'm using 30 FPS, I think what this be a good frame rate. I think what the game run slowly because the UpdateWorld for update all animations
If that's the framerate you're animating at, with a keyframe every frame, that may be too high (it depends how many bones there are, really.) Note that I am talking about the framerate in your animation tool when you create the animation, not the framerate of the game.
@ikg: Basically it's about setting up animation sequences. If you read the command reference for the Animate command, you'll notice you can choose which animation sequence to play. You can either setup all the animation sequences as one long animation and then chop up the frames using ExtractAnimSeq, or keep each animation as a separate file and use LoadAnimSeq to add the animations to your loaded model.
