Hi again :)
Ok third time (after THIS and THIS), now I have gathered a lot of info and found all the symptoms.

My laptop, HP Pavilion G6-2355SO, is sporting AMDs Dual Graphics.
With Dual Graphics the APU and the GPU works together to maximize performance. This works in theory, but not so much in reality. Disabling the Dual Graphics leaves me with the APU, and it does a good job, but I think I could get more out of my PC if I got to work with the GPU alone.
Having Dual Graphics on causes microstuttering, even though FPS counters show "high" FPS it feels like its much, much lower.
If I open CCC and click on "Switchable Graphics Settings", I can choose what graphics processor to use. "Power Saving" option uses the APU and "High Performance" uses APU+GPU, which causes massiv microstuttering. If I enable VSYNC it helps with the microstuttering only a little bit, but not enough. And using the "Power Saving" option leaves me with lag.
There is no option in the BIOS to disable or switch the main graphics processor.
I'm currently using Catalyst Driver 13.3 beta and have updated the BIOS.
CCC shows the APU as primary adapter, and the GPU as "linked adapter".
The APU, 7640g, has 512mb available ram, from which it shares from the same pool as my CPU. I have 6gb of DDR3 ram, 1600mhz.
The GPU, 7670m, has 1024mb of dedicated ram, DDR3 1800mhz.
My AMD 4 cored CPU runs at 1,9ghz with a boost up to 2,8ghz if needed.

I need a way to use the GPU. The GPU should work fine on its own, so I'd like to utilize it.
Any suggestions?

Thanks in advance.

Disable Dual Graphics but enable High Performance. See the last response:

Thats the thing, I have done that but its still using the apu. I get the same performance as I have Dual Graphics on but select "Power Saving". My GPU is as powerful or more powerful than an 4670, and the 4670 could play games at higher (not highest) settings without problems.

*Edit
I also get the same performance if dual graphics is off and I select "Power Saving" or "High Performance". The GPU is completely left out, unless I use Dual Graphics and choose "High Performance", but then I'm stuck with massiv amount of microstuttering.

I think I need to change the primary graphics adapter. But how do I do that?

Everything I can find says to disable Dual Graphics in the AMD Vision Control Center & to enable High Performance for the game. I don't have a dual graphics laptop so I can only go by what I've read, but it appears that each game's .EXE file has to be configured for High Performance. There is no one-click setting for all.

But why do I get the same performance in "Power Saving" and "High Performance". Selecting "Power Saving" selects the APU for rendereing, and "High Performance" should select the GPU for rendering, but its giving me the same performance. I have tried Black Ops 2, Metro 2033, Crysis 1 and 3, Far Cry 2, S.T.A.L.K.E.R. Call of Pripyat, Homefront and many more. Changing any of the EXE settings to "High Performance" or "Power Saving" still gives me the same performance. The only time its any different is when I have Dual Graphics on and choose "High Performance" for all the EXEs. But then its back to sh*tty micro stuttering.

Edit*
Actually, some games does run quite well with Dual Graphics. Metro 2033 doesnt have much micro stuttering issues, Race Driver Grid runs pretty damn good with it on. So, only games made with multi gpu in mind work well? or is it the "native" directx10 support?
never mind, it seems like there's no solution for my issue, as of now that is.
A for effort though.
