Dear PD-Community,

I am currently working on an media installation for a museum using pd and vvvv. The installation cosist of several visual scenes which switch after a certain time has passed and for each scene there is also an related pd scene. I use switch~ object to tunr dsp off for the scenes not used at the moment, but wheneverything is turned of in the init mode my cpu usage is still up at 60 to 70 %. I fear that if i add new scenes it will increase and that i will suffer from audio dropouts when scenes are switching( because than for a short time 2 scenes are active). Anybody knows better tricks to deal with cpu usage in pure data?

Thank you very much!

Remove any unnecessary number boxes / sliders, etc. , do not sample or compute things faster than you really need. For more advices, you should post your patch.

Dwan thanks for your reply! I am using abstractions which snapshot signals to check for output in each patch. I probably think this is causing the unnecassary load on the cpu.

Also i found out i'd put the switch~ object into a subpatch. So it only did stop computing audio in the subpatch but not the scene itself. Now everything works nicely!
