You might examine other possibilities as well. One big one is if you have a Pentium 4 processor. I've been fighting with CPU spikes in PD for a very long time now, and often find them related to denormal numbers. These are numbers very close to absolute zero, but not quite there, and are characterized by an extremely long series of digits after the decimal point, and which kick a P4 CPU into extremely slow and accurate mode. I found the problem to be much worse under Linux, but that doesn't mean it doesn't exist under windoze.
So, i've read some of the previous postings on this, and it surely sounds like that has happened to me. I read a tip about adding noise to critical sections of the patch, but can't really figure out how much and in what kind of situations. It would be great to see a patch which does this.
Otherwise, does anyone have any other practical tips in how to design a patch to make it immune against the slow and accurate mode?
thanks! Johannes
