CPU use in Sonar X3

Was having lots of dropouts/stuttering when mixing recent projects so did some research. Using lots of Plugins is the culprit, my laptop is a Quad Core AMD.

See the differences between CPU usage between the three songs.
Modern Lost Angel/Pantheon only on YGWIT, about 10 Sonar/Lexicon plugins on OLI, and 20 on the WAM one.

On the WAM mix, CPU #1 was hitting the red all the time and the other 3 were only slightly used.

ThreadSchedulingModel adjusted to 2 in Config file under preferences was helpful to reduce #1 CPU from overloading all the time. Now the CPU is higher on all four but #1 is no longer going into the red and overloading. Don't get the drop outs and static and choppiness so far. Fingers crossed.

This only works with Quad CPU or higher apparently.
 
I just upgraded to an i5, 16 gigs and X3 runs amazingly with tons of plugs.

Thanks for the tips about thread scheduling, though, glad you found it!
