Little stutters when playing Skyward Sword

[AnyOldName3]

Sound stutters happen when the game isn't running at fullspeed. If you use the absolute latest dev build (4.0-1442 at the time of writing), you'll find that there are better ways of masking this than in 4.0, and it might well run faster due to a load of major optimisations over recent months, so it's less likely to skip in the first place. You may find that you have to roll back your nVidia driver version by a few weeks if you use OpenGL, due to an incompatibility added recently. This might have been fixed, though.

Also, I can't see the issue in that screenshot, but there are a quite few possible causes of graphical bugs which have been eliminated since 4.0, so that's another reason to check the latest dev build out. It might help us to see exactly what you're describing, though, if you link an image at higher than 1x IR and without whatever scaling has happened to that one, or maybe a video.

As your original issue hasn't gone away, it could just be the shader cache being generated. As you get further into the game, or replay bits you've already done, you'll find this disappears. It'll carry across from versions 4.0+, so if you load the game back up in the latest dev build, and redo what you did in 4.0, you might well find it's gone.
