Hi,
On my Vista machine, I get an enormous instability of the framerate with
Gem, even if dsp is switched off. However, if I run PD with the
"-noaudio" flag, then the framerate is perfectly stable.
Is it normal?
When I say "enormous" I mean the time elapsed between a frame and the
next one often goes below one millisecond and above 80ms, though an
avarage of 40ms is always maintained.
I am testing this with the attached patch, which has only a gemhead and
a [realtime], so there's no actual processing of image or video.
If anyone doubts that it can be just the time shown by [realtime] that
is unreliable, note that if I run Pd with -noaudio the measured
framerate actually _is_ much more stable (rarely below 37ms or above
43ms a frame) and also, I have tried it with a simple video (homer.avi)
and I could note the jerky playing.
Isn't it strange that turning off DSP does not change anything while
running Pd with -noaudio does??
thanks
m.
