Check around on the cw forims, but a client of mine ran into this issue a
while back on a daw I had built for him, and after some research we
discovered that there is some sort of difference between the audio engine's
report and the total CPU usage from windows. I had found some information
on sonar 8.0, that was back then though, not sure if it still applies on
8.5. But from what we understood this was normal, or was being worked on.
Sonar 8 was built for better multicore performance, but they were still
working out the kinks in it.

Subject: [ddots-l] Sonar CPU Meter
Hi folks.
I'm using Sonar Producer 8.53 x 64, CakeTalking, Windows 7 etc.
I'm beta testing some software which appears, at least in Sonar, to bee a
CPU hog, and I need to report this to the company.
Sonar reports CPU usage around 50% when I have the plug-in inserted on the
master bus. However, when I go into Windows Task Manager and read the bottom
line, I get CPU values ranging from 18-27%, definitely nothing near 50%.
So, does anybody know why there is a big discrepancy here? Is one showing
overall CPU usage while another is maybe showing usage for one or two cores?
I have a quad-core CPU.
Heck, just for fun, I loaded a ton of plug-ins on a project, until I get
serious audio glitches. CakeTalking reports CPU around 98-99% in Sonar, but
back in Task Manager, it barely gets to 50%, usually ranging in the 40's.
what's going on here?
Chris
