CPU usage 45% at idle

All of a sudden Max/MSP is showing 45% CPU usage at idle – literally right after the app is loaded, with no patchers or anything else loaded.

Machine is a Dual 2GHz G5, 4Gb RAM, OSX 10.4.9

let me explain.

Done with and without the Java folder

So, I open even a very simple Sampling patch (seems to be related to Audio), play around, everything cool, CPU usage in the DSP status window is very low, not much maxing going around, Activity monitor reports very low use of Max/MSP.
At a certain point, as enunciated in the problems with Java thread, I get the spike: situation doesn

i’ve had issues using certain audio driver configurations that cause things like that. i’m not sure if that’s what’s going on here, but it would be worth looking into.
my problems mainly centered around ASIO configurations on windows that use multiple sound cards…

Just for saying I have the same problem.
It appears sometimes, I still didn’t understand when.

I experienced this with poly~. It appears that instances within a poly~ are
born un-muted. I loadbang a mute message on launch and my CPU load goes
back to normal.
