One Eye Jack: Let me explain a bit ... My timing routines in the main demo are Refresh Rate Independent and work perfectly smoothly (on the right video card) no matter what the refresh rate. It's been designed that way. The jerkyness we are seeing on these 6800s and my laptop appears even with that extremely simple code sample I posted above where the object moves a set (non variable) amount each frame (an integer number, not even a float!). Now if the frames are rendered in sync with the display (which BlitzMax/BlitzPlus is supposed to do for you) there shouldn't be any jerkyness but there is on some PCs and not on others. So somehow BlitzMax is not syncing with the display on all PCs, don't know why. In a sense you are right, the timing is out with the sync of the hz of the display, but in that simple example it's not "my timing" it's just a very simple method that should be fine.
