There are two possible sources of dropouts because of gem: first, gem
might run at less that 100% CPU usage but since itits calculations
happen only once per frame, the computation time is irregular and can
be smoothed out by using pd~ with a long-ish fifo size. This allows the
sub-process to get behind on computation and later catch up as the fifos
run out and refill.
Second, it could be that the gem patch sometimes runs at greater than
100%. In this case you can either allow it to get behind (I think this
will not just slow down the frame rate but also slow down pd's clock so
that sequences might also slow down) -- or else you can slow gem's frame
rate down until the computations fit -- and then you can go back to case 1.

Hi, List !
I stumbled over one question recently, regarding [pd~].
PD (with Audio operations) and PD with video (GEM) are best run in 2
seperate instances of PD, right ? (As video operations can cause audio
dropouts)
So, given these informations about [pd~], running a GEM patch inside
an audio PD patch using [pd~) is not going to be better than having
audio and video in the same patch, right ? (because [pd~] is
synchronous to its parent)
So, for an "asynchronous" situation, i still need to start two
seperate instances of PD to keep audio and video truly seperated ?
Thanks for clarifications !
Best
Oliver
