thanks for your reply! Is there some variable I could check to
determine if vsync is really on/off?

Of course, play_frame() also gets a dt value. How would you use this
for a smoother movement distance calculation? Is there maybe some kind
of pseudo code somewhere?

Well, I tried 1 pixel at a time, but it takes forever to move the pic,
even with unlimited fps...
