Here is my basic system:  HP AMD, 6 core with 10 gigs ram and Window's 8.  The problem is with Sonar Producer 8.5.  The Hyper threading works fine with Sonar 3, 5, 7, and 8 but just won't work on Sonar 8.5.  8.5 acts as if the hyper threading is turned off.  I've checked everything that I know to remedy the problem but no luck.  In the other versions of Sonar the cpu indicator clearly defines each individual core 1,2,3,4,5, & 6.  In 8.5 there is only one cpu reading.  The cpu is also high as it would be when the hyper threading is turned off.  Thanks if anyone has a suggestion or knows what is causing this.

Are you sure it is not just the CPUMeterMode setting?
From the help file
This variable specifies how the CPU meter appears in the status bar on multiprocessor systems. The values are as follows:
0 = The peak thread load is displayed as the bar and a yellow indicator shows the average of all audio threads. This the default mode.
1 = The average audio thread load is displayed as the bar and a yellow indicator shows the peak thread.
2 = A bar is shown for each audio thread. This is the same display as previous versions of SONAR.

Thanks scook, I think that is it.  I tried the large transport and all the threads were working.  I'll modify the cakewalk file.  The cpu did seem high.....maybe that threw me off.
