Screenshots From Nvidia Control Panel and Device Manager
I still believe that the incorrect graphic adapter detection mentioned in my first post is suspicious. Detecting Adapter #1 as having the combined ram of both my GPUs (6 + 6), and Detecting graphic adapter #2 as "Microsoft Standard VGA" (vendor id 1414) with 0 GB ram is plain wrong (note: I don't have an Intel or any other graphic card on my motherboard other than the two nvidia gpu's stated).
Please try and assign Graphics Card to Lightroom Manually.
Let us know if it helps.
