Thank you, BossDweeb! We have come to the conclusion "this is fault of the DRM Blocking malware MS has built into Win 10."
Sometimes updating graphics drivers helps; sometimes rolling back to older drivers helps. This has zilch to do with the issues those of who have hundreds of dollars of useless games on CD and DVD now. And if you are like me and live out in the sticks, downloaded games are not the answer on an internet connection that MIGHT hit 1.7 Mb per second before I am throttled back to 90 Kb per second.
