I only see the effect in the horizontal movement of both player and enemy ship.
The effect comes and goes too, it will be smooth for a few seconds then go back to jerky.
I can see that the enemy ships have different speeds, sometimes even the fastest onces have really rock steady smooth as glass movement but then they will go really jerky...you can see they are being moved 4 or more pixels at once and jumping back to a previous position just before they lurch forwards.
It isn't based on how may ships are on screen either, sometimes the screen is full of ships and the movement of them is really smooth.
The players ships missiles move to fast to make any judgement about graphical glitches, they appear to move several pixels at a time but I see no problems with the explosions...explosions are always smoothly animated.
[Edit] looking for filemon now...and I only get this stuttering with any program written in BMax, everything else performs as you would expect with a 6800GT.
