most everyone will have MS KB but i willing to be most people never never have microcode updates with the exception being the techy people that know how to do this and actual would do this updates. I have MS KB but not the microcode update cause asrock didnt release for my board yet. And what lil I test Shadow of mordor was done with AB on with all those power monitors enabled. while I might not of been getting my 60 fps out side rare occasions was getting when i last use this card, which was with much earlier driver. With these it was more in the range of 45-50 there was no stutter, it was butter smooth to me, granted in only played like 10 min after put everything back on medium. vsync was on no limiting though.
