seems where better of running are ryzens in Win 7 ...gotta love Win 7...
I quote
"I did some 3D testing and even thou there is not nearly enough data to confirm it, I'd say the SMT regression is infact a Windows 10 related issue.
In 3D testing I did recently on Windows 10, the title which illustrated the biggest SMT regression was Total War: Warhammer.
All of these were recorded at 3.5GHz, 2133MHz MEMCLK with R9 Nano:
Windows 10 - 1080 Ultra DX11:
8C/16T - 49.39fps (Min), 72.36fps (Avg)
8C/8T - 57.16fps (Min), 72.46fps (Avg)
Windows 7 - 1080 Ultra DX11:
8C/16T - 62.33fps (Min), 78.18fps (Avg)
8C/8T - 62.00fps (Min), 73.22fps (Avg)
At the moment this is just pure speculation as there were variables, which could not be isolated.
Windows 10 figures were recorded using PresentMon (OCAT), however with Windows 7 it was necessary to use Fraps."
