I have a laptop with an integrated graphics card as well as GPU (GeForce GTX 960M). As you can see in the image attached, when I enter into the PhysX configuration there is no connection between the GPU and any of my screens. In device manager the GPU is detected without any issues and on my control panel I see the occasional small spike in activity but no activity most of the time from the GPU. I am assuming there is a hardware issue? Any help would be greatly appreciated.
Hello and welcome to the NVIDIA developer forums.
This is more of a consumer GeForce issue so I recommend checking the dedicated GeForce forums.
Did you check the part in the control panel where you can chose which GPU should be used for PhysX?
In case that selection is not available you should do a clean reinstall of the NVIDIA drivers.
Thanks.
Depending on the HW layout of the laptop, there is NO direct connection between the discrete NV GPU, and any connected screen. The internal, and any additional external screens are ALL driven by the integrate Intel GPU. If an app is detected benefitting from the dedicated GPU, the workload will be move the the dedicated NV GPU, get accelerated by NV, the finaly content of the accelerated apps window will be copied into systemmemory, from where the Intel GPU sends it to any screen. (only this way a dedicated GPU can be disable to save power…)
A very few Laptops have specific screen output connectors hardwired to the NV discrete GPU, typically those that advertise with VR ready, since for such a usecase, it WILL NEED BO BE Nvidia to directly drive the HMD…
But you DO get the full NV gfx performance advantage from your setup, just not any scanout features, like HDR, warp’n’blend, or mentioned HMD capability…
