I'd say that the OS makes up for that. We saw in the previous test that Win 10 gave two extra fps over Win XP. Wouldn't be surprised if Win 10 gives 1 fps over Win 7 in that test.
Now that we have more optimal driver settings, that difference would be more pronounced. Couple that with a change in GPU brand to NVidia, this is as best-case a test can be for Green team. Also keep in mind the almost linear relation between "clocks:draw calls" on Intel CPUs.
CPU: Ryzen 1800x @ 4.0ghz (SMT OFF)
GPU: Radeon 290 (stock)
GPU Driver: 17.2.1
RAM: 32GB DDR4 2666 14-14-14-34 (rated for 3200 but won't run above 2666 no matter what)
MOBO: Asus Crosshair VI Hero
OS: Windows 10 Home 64-bit
Take any Ryzen results with a bag of salt atm. I ran this once and averaged 17fps, but throughout my numerous reboots I began only getting 14 fps. Then as I was writing this up, my test gave me 17fps again. What the frick?
I've been messing around with my setup since about 5pm ET today, and the BIOS for this Asus Crosshair mobo is a complete mess. When I first booted it up the CPU voltage was at 1.5+ pretty much constantly. Now it's mysteriously gone down, but I'm still getting strange results. Even at stock speeds it's pushing 1.4v when set to 'auto'. I've been in and out changing all sorts of settings and nothing ever seems to make much sense. Some changes don't actually take effect, some seem to cause other settings to mysteriously change, etc.
