Great read, oldbroad!
I especially like this one...
"The older your box, the better Windows 10 is," says Wardell. "So if you have like a Core i5 [Intel's mid-range CPU series] with a decent video card, you'll actually see a bigger gain than if you have some monster Core i7 high-end CPU."
Even with the caveat that a game must be "DXDIAG 12 aware," this is good news for people like me!
