Running Animation Choppiness

Have you suddenly found that when you run, things are looking incredibly choppy and movement seems to be stuttering?

Dave Yeisley, aka , has discovered both the cause and the cure:

You know the sound the game makes when your characters runs?
Each footfall was causing my game to stutter.

I changed the audio setting to miles fast 2D audio, problem solved.

Apparently the game waits for the sound to play before it will render the next frame of animation....

To have figured this out, you must be either incredibly lucky or just absolutely brilliant. The choppiness was especially pronounced while horseback riding.

[2D/3D Bias Adjustment]
I believe I've finally understood how to adjust the 2D/3D Bias slider which looks like this [2D---|---3D] in the Neverwinter Nights Game Options > Sound Options > Advanced menu. After clicking the "Test" button, you should hear two sets of bongo drums. The first bongo drum set is supposed to be the original sounds heard close by and the second set is supposed to be its echo.

Thus, after setting the Sound Provider to "Miles Fast 2D Positional Audio" as Dave suggests, adjust the 2D/3D Bias slider so that the two sets of bongo drums sound correct.
