Pretty slow on my machine, too (flips between 19>21fps and 30fps). MacBook Pro 3.06GHz GeForce 9400M MacOS X 10.6.1
I was starting to think that Iterator performance was slow, too, actually, from other experiments, though I haven't done any formal tests. It's disappointing though- I had hoped that Iterator performance was one of the things that might have been sorted out in QC 4. a|x --- On Wed, 4/11/09, Christopher Wright <[email protected]> wrote: > From: Christopher Wright <[email protected]> > Subject: iterator performance > To: "quartzcomposer-dev list list" <[email protected]> > Date: Wednesday, 4 November, 2009, 19:48 > <puts on asbestos suit ;)> > I'm finding a lot of cases where iterator performance in > QC4 is dramatically worse than in QC3 (typically about half > as fast). > > (this does a 50x50 grid, with > half the sprites disabled, so it's 2500/2 = 1250 sprites per > frame -- MacBook can render this at 60fps in Leopard, > MacBook Pro is struggling to hit 30fps in Snow Leopard.) > > (this one's iteration count > is cranked up really high, but it's still ~5fps on my > MacBook 1.83GHzGMA950 running 10.5.8, and only 2.2-2.5fps on > my MacBook Pro 2.4GHz 8600M GT running 10.6.x (the MacBook > on Snow Leopard also hits about 2.5fps, so the same machine > is half as fast in iterators).
