Hi,

I own Asus UX32VD which has integrated intel hd4000 gpu compatible with Intel Quick Sync and discrete nvidia GT 620M GPU which support OpenCL and CUDA

Is there a way to be using both nvidia and intel GPUs ? (GPGPU)

If i don't force powerdirector to use Intel GPU though the nvidia panel, i can't use Intel QuickSync

One or the other but not both. .

So the multi gpu is only for SLI gpus?

One or the other but not both, that's just not true for the laptop platforms I've used. It can be finicky to get things correct from a platform point of view(BIOS, drivers, Dell, Asus....), but that's not really PD related.

I've had success with both Nvidia and ATI cards in a laptop and successfully used both with CL OpenCL. Keep in mind, CL OpenCL set in preferences is not a generic timeline encoding accelerator but only accelerates HA capable video effects as the option indicates in preferences. The attached pic shows the FirePro M6100 at 100% and the HD4600 at ~50%. Net effect, 2:05 encode time vs 3:10 for HD4600 QS only so it can be advantages IF the timeline has extensive use of HA effects that take advantage of CL current OpenCL implementation.

I guess I am not brave enough to try that nor do I really need to go faster. Apparently what you have suggested is possible with certain chipsets. It is not for the random user. I didn't really read the article supporting your process thoroughly but it says it is possible.

http://superuser.com/questions/241157/how-can-i-enable-onboard-graphics-and-dedicated-card-simultaneously

What was the quality of the video using the dual chipsets same as the ICS, the card chip set or different than both.

It's not my process and the thread you reference was for a Presario desktop, desktop graphics and graphic options configurable to the end user are nothing like laptop graphics. Sony typically credited as the process pioneer of switchable graphics on laptops with the Centrino 2, 2008 timeframe.

Random user? Any user who has bought a laptop with Intel supported HD graphics and also a dedicated GPU for the last several years may have some capability. What capability the laptop has concerning PD12 multi-GPU capability is up to the platform supplier and probably worked as advertised when new. Some suppliers turn the Intel HD graphics off and don't allow enabling through the BIOS, like a given Asus laptop user on this forum found out as they struggled through discrete laptop graphic card woes with PD12. Some platforms allow switchable graphics, some run Optimus, others not. So as I indicated, it is not a PD related topic, just basic laptop technology used/supported differently by various platform suppliers and PD can make use of what hardware capability you have.

laptop with Intel HD graphics only, my experience is PD will use it
laptop with discrete Nvidia or ATI graphics only, my experience is PD will use it
laptop with Intel HD graphics and a discrete card, my experience is PD can use both as my pic had shown subject to the clarifications I had made for PD12

Visual quality and audio sync of this test clip I did to show proof of capability within PD was the same as using the HD4600 and QS. I used the H.264, 1920x1080 (28Mbps) standard PD profile during the test and my selected profile bitrate was verified in the produced output file.
