If you want to be generous, then it's because optimization work is now focused on Turing and Ampere rather than the 2 generations older Pascal. GALAX GTX 1060 6GB EXOC with some overclock (Max temp 86 c) but usually doesn't get that high when gaming) Intel Core i7 8700K Ghz (Max temp around 85c ish. So I was running into severe performance issues lately and it turns out that for some reason my GTX 1060 6gb didn't like the new drivers and going back to driver version 442.74 completely fixed 'almost' all of my fps issues, so I was wondering what could be causing my GPU to run so badly with the latest drivers? I tried it on two separate installations of windows and in both cases it ran badly, I tried it on windows version 2004 and 20H2 and both ran really badly and only when I finally reverted to the older driver that It worked well again, so I'd like to ask why this happens, honestly at this point its more out of curiosity than anything, If it can be fixed that would be great but otherwise I'm fine using older drivers, I just would like to know why this is happening.
