Re: [pygame] from Python+Pygame to C+SDL, Any experiences?
This is a problem with pygame (no flame intended), because if I'm not mistaken games in SDL can have smooth scrolling backgrounds.
This in one reason I am moving to openGL, with pygame for input.

The first is where the whole window or screen really is being updated every frame - think of a smooth-scrolling engine like an overhead real-time strategy game or a side-scroller. So what do you do in this case? Well, the short answer is - don't write this kind of game in pygame. The long answer is to scroll in steps of several pixels at a time; don't try to make scrolling perfectly smooth. Your player will appreciate a game that scrolls quickly, and won't notice the background jumping along too much.
