I'm working off from Derek Pierson's tutorial series, and in his Skybox Render() sub he declares these matrix variables and assigns these other properties.
Dim
worldMatrix As Matrix = Matrix.Identity Dim viewMatrix As MatrixviewMatrix.M41 = 0.0F
viewMatrix.M42 = 0.0F
viewMatrix.M43 = 0.0F
Since they don't ever change during application run, I was thinking they should be declared just once as class level instead of per frame.
How much performance difference would a small change like that make
Is better to declare as class level variables?

Not a whole lot. Creating an instance of a class is NOT the hard work being done by a DX app. But, it makes sense, so try it and see if you can notice a difference. It will at least make the code cleaner.
