I know this is an older post, but just wondering what resolution are you using for your game? and is there action going on,on top of these background images?
I'm trying to do 1920x1080 backgrounds for a space action shooter. And when my backgrounds are png or jpg, it slows the framerate considerably.. I get about 46fps and it's visible in the action. All sprite movement seems to pause for a nano second or 2 making it look jumpy.
when I export the game to run on Mac OSX or Windows it's fine and there's no framerate issue. But my tests are all in dropbox, so maybe that could be the issue? But I wasn't having this problem until I upped the resolution (from 1280x720) and added new background images.
any suggestions would be helpful!
