I reckon its core parking - W7 will force all traffic down one core until it needs another so you wont see much hitting the other cores until you max out the first. It was supposed to be more efficient way to manage power, but its crap for DAWs. There was a registry hack for it posted a while ago and it worked a treat.

Didn't get anything on Core parking on that link

I have a Quad Core PC, the "performance" toolbar shows only 1 bar for CPU usage.  My buddy has the exact same system, his shows all 8 bars in the CPU usage. 

A quad core should only show 4 bars in the performance section, not 8.

I have a 6 core and does pretty much the same. Seems to use the first core more than the rest. However the more I add to the project and more load I create, the other processors get used and the meter shows it.  Have had zero issues related to processingon this machine. And I have created some files with tons of effects/plugins etc.  I would suggest loading your craziest project and take a look at it.

Yep that worked.  I loaded a big file and added 4 more Omnisphere tracks and the other Cores started showing.  Thanks for the tip ; )

As someone above said.

 If you think Core parking might help as well try here, worth a read.

A quad core + HT (hyper-threading) will show 8 threads. Always has in my Win 7 environment.
