APU vs GPU HP Pavilion laptop (again)

Specs: Windows 8, 1.9 GHz / 6144 MB
Hi, this is a followup to my earlier thread http://www.computing.net/answers/ha...

I have a laptop sporting AMD dual graphics, meaning the APU inside A8-4500M renders stuff with a 7670M. It would have been great if it actually worked.

I recently tried playing some games with dual graphics off, only using the APU since CCC doesnt give me de option to disable the APU and use the GPU, and it ran just like It did with dual graphics on. So my conclusion is that for some reason the GPU, during dual graphics mode, is left idle.
How can I use my GPU then?

Ok this time I dont want a half assed answer.

Well, I'd love to but I cant, thats why I came here cuz I could find the answer myself.
And the half assed stuff was on my last post, the only answer I got was to a web site that didnt help with ANYTHING.
My question is "How can I utilize the GPU instead of the APU?"
I've already stated that CCC only gives me the option to disable the GPU when turning Dual Graphics off. I hope you can see my frustration.

I think the point of the answer to your previous post was to demonstrate that your theory, that you would get a performance boost by using just the GPU, was the opposite of the facts demonstrated by testing. That would appear to be a useful answer to both your previous post and this one.

Perhaps if you can't find the answer, and no-one here seems to be able to either, there is no answer? But I expect that this is just another half-assed answer! :)

You still havent answered. I cant use the GPU because CCC doesnt allow it, its either GPU+APU or APU... Come on people!
I'll ask again, HOW THEN CAN I UTILIZE THE GPU AND ONLY THE GPU?!

You normally disable integrated graphics in the BIOS, but many modern laptops using AMD chips do not allow this option - they just allow integrated or both, but not GPU only (makes sense as although many may want the power savings of the integrated graphics few would want the performance decrease of using just the GPU with no other gain).

Although you don't actually tell us the make and model of your laptop (information that would obviously help to obtain an informed answer), I presume that this is not available on your computer. The other thing that you could try would be to disable the integrated graphics in Windows Device Manager. This assumes that your monitor is connected to the GPU, not the integrated graphics adapter.

PC Model: HP Pavilion G6-2355SO
Display drivers in device manager are listed as so; "AMD Radeon HD 7640G + 7600M Dual Graphics" and "AMD Radeon HD 7600M Series".
I presume the second one is the "GPU" driver and the first one is "APU+GPU"driver, but its kinda weird having them separate.

*edit
I tried to disable the 7640g+7600m driver, that left me with windows basic driver according to dxdiag, and disabling the 7600m driver didnt do anything... back to square one.

You've asked about this at least 3 times now. What is it that you don't understand? Unfortunately, Dual Graphics aka Asymmetric CrossFire doesn't work very well, especially for gaming, due to "Micro Stuttering". You were provided a link in one of your previous posts. All you have to do is disable crossfire in the CCC & choose which graphics you want to use. Have you tried updating the graphics drivers & CCC?

Riider, the reason I want to use the GPU only is because then I'll get rid of the microstuttering (if there where any to begin with, since it's just rendering using the APU). and my drivers are 13.1, I did try the beta 13.2 but that caused weird water glitches in crysis 3. And I cant choose which one I wanted, its either GPU+APU, or APU. the the GPU+APU option doesnt work.
Again I'm only looking to use the GPU, not the APU.
The APU is criminally slower than the GPU (well duh) and my problem lies with the dual graphics mode not using the GPU at all.
I'm frustrated, I have a perfect (mostly) chip just sitting there, doing nothing while the APU tries its best at tasks its not supposed to do, or not good at.

If you want help on a free forum insults are the worst way to go about it.

Always pop back and let us know the outcome - thanks

Derek, if you don't have an answer (or a suggestion, or something that might help), then don't comment. Its not helping anyone.

I've noticed. And it seems there's no solution, tried everything I got here and what I thought up, still nothing. Damn, Dual Graphics has potential, but not when it leaves the GPU idle.
Still, gotta give the APU credit, most games run kinda smooth, kinda.
