Is this posible? From the [dsp], i get cpu usage peak load prices from 4% to 220%++, and 10 to 100% average prices. While running ReacTIVision.

I have a MacBook 2.1 - Mac OS X 10.6.8 with 2GB ram at 667 MHz, 2GHz Intel Core Duo Processor.

I mean its ok high prices but over & 2 times higher than 100% is not logical...

I've never used [dsp], so I don't know how accurate it is. I always just use OSX's Activity Monitor.

Ok, this is also crazy.

On osx monitor when i use only pd extended/ dsp-audio off , is about 2% usage.
When sound is on, tis about 18~25% cpu usage.
a when i open reactivision with sound off, pd uses from 50 to 95% cpu usage, and reactivision 30~40%.
If i also switch on the audio, the i have pd using the 110% of the memory and Reactivision another 40%. (150% all the processes together?!!!).

In reflection to really what 's happening i receive the sound with about 4 seconds latance, clipping and not stable until pd crashes down.

To say the truth i don' t know much of mac computers but mine has about 1.5GB free disc space, and i know that on a windows system this needs either defragmatation or format but for mac i really don' t know

a few possible ways to improve your performance:

1. try increasing your latency. (menu->preferences->audio settings->delay)
   by default it is probably set at 50ms. try increasing to 100ms or even 500ms or something.

2. use JACK for your audio.

3. i just looked at a video demo of the reacTIVision system for pd, and by the look of it, there are lots of console prints and gui number boxes being updated continually. If you remove those un-necessary gui objects and console printouts, it may help.

not sure how much help those things will be, but i would definitely try running with JACK. just google 'JACK' if you don't have it already.

Thanx. The truth is that all my previous problems where runnig without any gui and console messages, as far as it concerns reactivision. As for now with jack running and 500 millisecond latency is running fine, but the cpu usage is almost at the same levels.
I am new in pd and i don't know if when my whole program that will include about 30 patches (i am at 20 right now but i do my trys using 4 or 5 of them) which 10 of then will be sound sources running simutanusly will affect the system or not ( i also expect great latency but that 's ok).
Anyway, i 'm thinking of running reactivision on a different pc and send tuio messages via vpn connection to the macbook.
Thanx again..
