I have PD16, Dell XPS15 laptop with i7, NVIDIA GeForce GTX 1050 with updated drivers.
I can use the NVidia control pannel and go to program settings and select Cyberlink PD for the program, but on 2. I cannot select anything other than Integrated graphics. It won't let me use the down arrow to select anything. I can select other programs and then 2. I can pick the NVIDIA processor. Heck, I can even select Firefox from the drop down, but none of the PD programs like PD16, PD screen recorder.
I have also disabled the internal graphics to the system would force use of the NVIDIA, but then it uses the CPU insted of the Intel GPU or NVIDIA.
In PD16 under settings, I have it set to use hardware accelleration also.
However, under the NVIDIA settings, it says what is using the GPU and it never shows PD16. Under task manager, when I use PD16, it shows all the load on the Intel internal GPU, or if Intel GPU is disabled, it shows the load under the CPU. Nothing shows it under the NVIDIA>
