Blitting with hardware acceleration is only supported in xlib NOT in SDL. The Size of the tiles should be big. I used 128x160 in a 640x480 resolution. Speed tests:
SDL: 32x32 tiles -> 13 FPS
128x160 tiles -> 3 FPS
xlib: 32x32 tiles -> 12-13 FPS
128x160 tiles -> 35 FPS
You can try it for xlib. Scale bg.png up an down. You will notice the difference Link to source: [1]
