When you scroll one pixel to right for example (slowest scroll), you have to scroll 50 pixels each frame to get a fluid scroll. if this shift of 50 pixels to the right per second is too fast, then you have to divide it by a value, most logical one is two, so you do 25 pixels shift to the right per second, so, one frame shift, one frame idle, one frame shifts, one frame idle, and so on, this way, you get 25fps shoppy scroll. It's like that, you can't do a slow scroll, that is 50fps.
What? That would only be valid if Gods scrolled at half of a pixel per frame (which it doesn't), and even if it did, it wouldn't be choppy at all. Choppiness happens when you drop frames that would have been there.

Resolution has absolutely nothing to do with this, and dropping frames doesn't affect scrolling speed. It only makes it choppier. You could "turn the page in 6.4 seconds" at one frame per second!

Higher resolution does make scrolling look smoother, but what does that have to do with this?

You imply that you're a coder? Or that I'm one?

Turrican II and Battle Squadron have far more objects, and they scroll just fine. Besides, Gods scrolls badly even when there's nothing on the screen. It's bad coding, plain and simple. And I like how you "doubt" that smooth, slow scrolling is "possible", when the Amiga has numerous games that do just that. Actually, scratch that, MOST games on almost EVERY system do that. That's why people can tell when a game DOESN'T.

What's that even supposed to mean?
