Premiere Pro CC & Media Encoder GPU acceleration problem

Report · Nov 21, 2016

After 2017 update, my system (S.O. Windows 10 Home, i7-4710HQ, nvidia gtx850m) take an extremly longer amount of time to render - same settings - than before the update. I immediately thought it could be a problem with the GPU acceleration, even if either in Premiere Pro project settings and in Media Encoder the mercury GPU (CUDA) mode was selected. So I thought that maybe it could be a problem with the lastest video driver (375.95) so I made some test rolling back version until v.368.22, with no changes.

Testing the system with GPU-Z, just to have an idea of the GPU load during some rendering, I figured out that the gtx850m GPU is not used at all and the same occur at the CPU, but the integrated Intel HD4600 is maxed out, running 100% load all the time, and the same occur even if I select the Only Software Mercury Engine mode.

Any suggestion?

The GPUsniffer report an initialization failure (the same with any version of driver tested):

Welcome to the club! Most people with dual GPU are having this issue including me on laptop with AMD Firepro.

At least I'm not the only one with this problem, although it is not a consolation, I'm hoping that is solvable, since it showed up from the 2017 upgrade.

Well, I don't feel alone anymore... I use an octa-core, and it's taking more than 10 min. to render something that I used to render in 50 sec.!

I figured it out. At least for me. I have an AMD R9 270X and an Intel Integrated Graphics. Turns out PP CC 2017 could initialize the Intel card. I realized that by using the GPUSniffer.exe. Then I simply went into my BIOS and disabled the Intel Graphics Card. And ta-daa, it worked. Hopefully it will be a solution for you guys, as well!
All the best!

I've alreay tried to disable the integrated intel graphics via software, the GPUSniffer so can initalize the 850m but, even if the mercuy CUDA accelerated mode is selected, encoder cannot utilize the Nvidia card rendering all the things on cpu , neither premiere or illustrator and so on...

I'll try to do this via bios, maybe something will change..
