Hallo,
is there a kind of equivalent to the "-audiobuf" option of Pd's audio system in Gem? I sometimes run Pd with a large audiobuffer when I'm also using Gem to avoid clicks, but then the graphics updates seem to happen earlier than the audio signal arrives which is something I would like to avoid.

a workaround i mostly use to avoid this trouble is to run two
instances of pd, one for the sound and the other one for gem (with
dsp 0). then comunicate between them via netsend or OSC. this is
working very well.
ciao, max

I should have mentioned: This is no alternative for me, as I generate a lot of data that is shared between the audio and the graphics part and cannot be sent over the net effectively. Also I don't see how it could solve the problem of two different latencies, if the audio-Pd's latency is set high while the Gem-Pd's graphical latency is still the standard one.

if separating gem- and audio-part in two instances of pd, you could run the audio-pd with -rt and low latency, so both are 'fast'.
of course, this would work only, if there is a opportunity to split audio and gem, which is not the case in your project, as you mentioned.

i usually send all msgs to gem objects through one message-channel, which can be easily run trough a pipe to delay the video to compensate for audio latency. this latency compensation is also necessary when performing in certain big spaces because sound is travelling much slower than light.
