I assume you're not talking about "priority" in the Unix sense. If you
simply want to relief the system of some load by limiting the QCView's
FPS, you could use -setMaxRenderingFrameRate: on your QCView. The
default value is 60.0, iirc.
You should bear in mind that the effect this has on the overall
performance of your application depends on your composition. If you
are mostly doing some rendering in the composition, you won't see that
much of a change because that is done by the GPU. If you use a lot of
patches to implement some logic in your composition, this could maybe
help you.

Hi,
I'm running a Quartz Composition, while the app does other tasks.
How can I lower the priority of the QCView so it does not slow down
my other tasks (even if the FPS strongly drop)?
All the best
Christoph
