Thanks for the reply.  I saw something interesting in our GPUSniffer results. At first, I thought the bug is that Adobe Premiere Pro CC always use the first GPU it detects.  Then again, I don't think Adobe engineers would make such a low level mistake. Now, the GPUSniffer doesn't indicate which GPU is the integrated one and which is the external/dedicated one.  And it's almost impossible for the code to detect all the models of GPUs.  There is a possibility that the code is using the Total Video Memory to decide which GPU to use.  Since integrated GPU shares the memory with the system, chances are that it has more Total Video Memory than the external/dedicated GPU as shown in our GPUSniffer results.  I can't prove this because I couldn't find a way to limit the memory for the integrated GPU. In any case, I am sure it would be an easy fix if Adobe makes this a priority bug. ... View more

I think this is a bug in Adobe applications.  It should be very easy to detect internal GPU and external GPU in C++ or Java code.  All game applications do that.  As a matter of fact, Adobe's own GPUSniffer detects that too.  But Premiere Pro CC 2018 ignored the results of GPUSniffer or it simply doesn't work with GeForce GTX 1080.  As you mentioned, it doesn't work with older GPU that's on the "recommended" list either, so this must be a bug in deciding which GPU to use in Premiere Pro CC application. ...

I have the same problem with my new Dell XPS 8930.  I tried all the suggestions listed here and other places.  None of them work.  Here is what I found: Premiere Pro CC 2018 always use integrated GPU (Intel UHD Graphics 630). If I disable integrated GPU, Premiere Pro CC 2018 will use CPU instead of GTX 1080. Have both GPU enabled, there is no difference in setting CUDA in Project Settings in Premiere.  Choosing "Mercury Playback Engine Software Only" would still use internal GPU. The games are running fine with GTX 1080 on my machine.  I think this is a problem with Premiere Pro CC 2018.  Looks like Premiere is not compatible with GTX 1080.  I sincerely hope Adobe can fix it! Here is my system: 8th Gen Intel i7-8700K Processor (No overclock) nVIDIA GeForce GTX 1080 8GB 1TB M.2 SSD 2TB 7200 RPM HDD 64GB of 2400MHz DDR4 Memory Windows 10 Home 64-bit * When both GPUs are enabled. * When internal GPU is disabled. ...
