Good feedback. Yep, that is exactly what I did, and the demos worked.
The last step for me is the TDR edits, perhaps needed because of the bulky simulation I was trying. TDR is more of an issue if you have only 1 GPU that is being shared by Windows (for its visual display) and by some application attempting to hog it, like Accelerad or some GPGPU software. If the GPU becomes so busy that it prevents Windows from being served by it, it throws an interrupt.
So I have 2 options: (1) disable TDR w/ regedits and hopefully thatll work (2) perhaps prevent Windows from using my Titan Xp card and just use the onboard Intel one, and then use the Titan just for this type of processing. I haven’t tried either yet - but I am hopeful that one of those will work
