GPU acceleration for Premiere on GTX 780 grayed out
Hi, I have been all over the forums and have not found a solution to this issue yet. Basically GPU acceleration (CUDA, Mercury Playback Engine) cannot be enabled on Premiere or AE although it appears my graphics card is supported by Adobe. This seems to have worked in the past with this machine so something new must have broken it. Specs are below:
Windows 8.1 Pro x64
Intel Motherboard
Core i7-2600K @ 3.4 GHz
32 GB RAM
NVIDIA GTX 780
NVIDIA Driver version 391.35 (latest as of today)
So far I have tried
Updating Windows
Updating Adobe CC suite
Removing, uninstalling, deleting the NVIDIA drivers, and reinstalling with a new version of the latest driver several times
Updating the Chipset and other motherboard drivers (Intel shows all up to date)
Onboard Intel graphics disabled (done previously, does not show up in device manager)
Forcing the gtx 780 GPU in NVIDIA control panel 3D settings
Modified "C:\Program Files\Adobe\Adobe Premiere Pro CC 2018\cuda_supported_cards.txt" to explicitly list my card in every imaginable way (file did not exist so I made one - no change)
Ran GPUSniffer and get this result:

Adobe Support said I need to upgrade to Windows 10 but I don't see why that would be necessary.
Thanks in advance for your help.
