Hi Folks,
I've gotten my own effect up and running and am seeing a really bad frame rate. I started with the Dimmer2EffectWindows sample (and
eventually commented out *all* of the pixel-pushing in the EffectFilter* files).
- My source media is 1264x720, 30 fps.
- On my system I can play two of these simultaneously with no apparent performance hit (roughly 10 mbits/sec).
Even the simplest effect (even a complete NOP applied to only one source, for that matter) causes the frame rate to drop to 15 fps
or less.
Is this simply due to moving a complete image around in RAM, rather than changed pixels per frame? Is there something I've missed
that would cause this?
Thanks,
Chuck Bueche
