Dear Stefan,

I notice that in the GPU Z Window, there are Physx activated with Open CL, is it only Intel HD Graphics use or with Nvidia GPU, because for CUDA tab is not activated ?, if there is NVIDIA GPU, of course both for the CUDA and Physx will activated , but in GPU Z only Physz. Please explain for the GPU use . Thank You


Screenshot was from an Optimus laptop.
I think fields should have an Optimus hint.
I asked the author.

Quote from: W1zzardPhysX is a system-wide capability

For comparison a screenshot from GPU Capsviewer and GPU Shark.
I selected IGPU in NVIDIA control panel for both global and program setting first and still Intel is detected as second GPU.

Also check out this article from the author of Shadertoy, who confirms that Optimus technology is a PITA.


Ok, I just wonder which one of the GPU is activated Nvidia or Intel ?, because the GPU Z show for Intel, but The CUDA tab is not activated, but the Physx is activated ?, also my question now , If  I use my desktop with Intel Processor, 2 GPU : Nvidia and AMD on Windows 10 64 Bit, Is it capable of use 3 different GPU ?  Intel HD, Nvidia, also AMD GPU as Multi Adapter GPU Configuration ?, Please check, If capable, I remember that the Nvidia Driver also states and not activate if there are other GPU present especially in Desktop configuration. But in Windows 10 there are Multi Adapter Facility Right ?, because I'm wonder how ?. Thank you....


If you select IGPU in NVIDIA control panel, both are active: Intel for rendering, NVIDIA for computing.
I'll check later if that speeds up things.

Multi-adapter rendering is still in its infancy, check out:

Dear Stefan,

Thank you for your reply,

1  what I mean also is If I use for example AMD Radeon HD 285X for rendering ( True Audio being use ) + Nvidia GTX 950 for rendering ( including Physx use ) in the same time also with Intel HD 530 for compute , is it capable or not in Windows 10 ? Assuming there are 2 PCI Express x16 to be full used with AMD Radeon  + Nvidia GPU , + Intel HD GPU, assuming Explicit Multi Adapter were implemented in it Please investigated with AMD or Nvidia.

2  If I use Windows 10 with above configuration, but I play Directx 11 Game, is it capable to use ? because in Windows 10 use Directx 12, but game is still use Directx 11 , I mean for the configuration AMD GPU + Nvidia GPU + Intel GPU, in the same time

Thank you


I looked around further on the net:

recent NVIDIA drivers block AMD, i.e. you can't use them together.
A hack can be found here
but i didn't read all posts how well it works

From my understanding multi-adapter rendering is not provided automatically by Windows 10, but must be programmed into each new application.
So older games/apps need to be updated.
