Task Manager Question

Firstly apologies if this is being posted in the incorrect forum.

I recently installed the AMD Dual Core Optimizer on my FX-60 rig.
To see if it was making any difference I loaded some games and then "Ctrl-Alt-Deleted" to Task Manager whilst the game was running, to take a look at the "Performance" tab.
I noted that there were 2 graphs to represent the 2 cores.
On some games, both graphs were running at the bottom of of each graph whilst CPU usage was at 0 to 3pct. Other older games had the left graph running at almost the top of the graph whilst the right hand side one was running at the bottom. CPU usage was 50pct.

I don't understand what is going on here. I would have thought that both graphs should be showing CPU usage if both cores are being utilised.
Am I mistaken in my belief ?
Is the Dual Core Optimizer not working or have I completely mis-understood it's use ?
I went into my BIOS and noted that "Cool and Quiet" is enabled even though I have not installed the appropriate software from the AMD install disc.
Perhaps that is the issue ???
Should "Cool and Quiet" be disabled ?

Should I be doing something different to see if both cores are being used ??

Appreciate all advice given

cheers
 
dual core optimizer only fixes some issue's that a few apps have with dual core.

i installed it as cs:s would skip constantly and not give constant performance, this is because of the way the cpu works within windows and how it handles the distribution of load between the cores or something similar lol, been ages since i read up on it.

anyway, the optimizer just fixes that issue and lets apps run smoothly.


as for the graphs, 1 graph per core.

some games when you alt tab will release the cpu cycles hence why the graph is at the bottom, some older games dont which is why its still at the top. very few games are made for dual core so they will only use one core.

50% cpu usage is 100% usage of 1 core, 100% cpu usage is 100% usage of both cores.
 
Thanks for taking the time to reply.
I was thinking when I "Ctrl-Alt-Deleted " perhaps the game stopped running.
I just ran Call of Duty 2 and noticed that both graphs were running around the middle of the graph but CPU usage was still 50pct.
I note that is the case even with games that are optimized for dual core, for example Quake 4.
