[QUOTE=Greg] So a single frame sprite object is more resource intensive than a same size tiled bg?[/QUOTE]
A single sprite object is almost identical in performance - not faster or slower - than a tiled background of *any size*. So a tiled background object showing 100 tiles (10x10) draws about the same speed as a single sprite. Which means if you made a 10x10 grid of sprites, the tiled background would be about 100 times more efficient!
