Hi,
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:

What can be the reason for this problem?

Have you set up double-buffering?

I'm using 25fps and get smooth animations most of the time. I'd imagine that 25fps will get you there for the majority of effects.

Cheers,
