100% cpu with oscP5 and void draw()
May 24th, 2005, 8:16pm  
hi.

I've been trying to use oscP5 to connect processing and max/MSP.

Playing with the examples provided, i had a problem discussed in another thread (both programs comunicating correctly but nothing showing in processing screen). I eventually solved it with sojamo's explanation (add an empty void draw() function to the example's code), but...

with that solution i get 100% cpu consumage with processing. Is there anything i can do to solve this?

Thanks a lot.

If got the same problem. In some cases the process priority of the sketch task is high instead of normal. But I dont know why.

unless it's the osc library, it's probably because with an empty draw loop you're getting a framerate of 100+ fps, which is making trouble. try setting framerate() to 30 or even 60 to see if it gets things under control.

hi,
i checked the cpu issue on pc and mac and it looks like on my mac cpu increases big time.. not to 100+ but almost. but if i set a framerate to 30 or something, cpu usage goes back to normal, so the framerate is the key, and the empty draw method is the evil.
on pc though without framerate i got 4% cpu usage and with a framrate of 30 i got 2%. so it seems no problem on pc then, but on mac.-

well, curiosly enough, i'm on a pc.

anyway, i checked it here at work and setting framerate(30) solves the problem. I'm sure it will be the same at home.

Thanks a lot. I'll continue my max/msp > osc > processing journey.
