I just recently re-installed, with a fresh copy of Win10 1607 Home, and this box has a G4400 @ 4.45Ghz, and a 7950 3GB.
I was about to comment that my scrolling is choppy in my web browser, as bad as Linux is on my lesser machines.
Then I remembered that was doing DC on my video card. Still, I was before I re-formatted, and I don't remember any visible browser lag from it.
Edit: Hmm. Nope. I set my DC to stop doing it on the GPU while the PC was in use, and I still don't have my glass-smooth scrolling back. There's visible tearing when scrolling. Weird.
I'm probably not using the same Radeon Crimson drivers that I was using before. The current ones were automagically installed, when I re-installed Win10.
Edit: I think I must have had a GPU crash while the PC was sleeping, or perhaps when it was woken up.
I had to re-start GPU-Z, as the sensors for clocks and temps weren't reading at all. I re-started Waterfox, and the hardware scrolling came back.
More strangeness with Win10!
