I render a composition with QCRenderer at about 70fps (according to FPS display), but it doesn't look smooth. In the QC App and as a standalone screensaver the composition is smooth even with 60 fps.
I checked, the times passed to renderAtTime: are smooth values with distance about 1/70. It looks like QCRenderer renderes 70fps, but not all frames are displayed within the view.
I call [openGLContext flushBuffer] immediately after renderAtTime:

try changing the vsync (swap interval) to 0 or 1
