I think it actually appears smoother if you do it faster; the eye is fooled
better. That's why I was encouraged enough with my early playfield
animation experiments to start that Ballblazer game I never finished.

I think as long as you update them often enough that the eye only detects
the minimum possible 4-pixel jump (allowing you to scroll a screen
completely in about 2 seconds) you'll be fine. Jumping two playfield
pixels (8 regular pixels, 1/20th of the screen) per frame would start to
get choppy but hopefully in a game that scrolled that fast, the player
wouldn't have time to notice ;)
