I am in slow ring, I like the stability of build 15058 current insider ISO, fresh install smooth as butter but WAS NOT until FRESH INSTALL. Screw upgrade process never again.
Better frame rates in most games I have been testing including Assassins Creed 1 through IV, BF4,BF1, COD Black Ops I - III, ARK, Borderlands series, Deus Ex series, list goes on have around 200 games through steam on an eSata drive @ 6gbs 3.5" 4TB HD. Currently using Assassins Creed series, BF4, and BF1 on Crucial X300 SSD as those are my favorite lol.
