I'm trying to get smooth movement in my game, right now every couple of seconds the moving square jitters.

I'm using C++ with SDL2.

I made a very simple project to test different methods so all that's happening is a box moves across the screen.

Here's a pastebin of the code

Here's a link to a dropbox folder containing the 'game'

Any input would be greatly appreciated, and let me know if you need any more info.

Thanks!
