Is anybody else seeing choppy performance in NX 8 sketches?

What it says on the tin.

From time to time rotating a sketch in NX 8 (in both the sketch task environment and direct sketching) will become very slow to update, both to 3D mouse input and regular 2D mouse input. The display will update every few seconds, but appears to be "listening" to input in between.

Is anybody else seeing this issue?

SpacePilot firmware 3.12, 3DxWare 10.0.11, 3DxWinCore 17.0.19.
