Windows 8.1 had some awesome features, acceptable. But why is it going to be hated by someone, especially gamers?! Yes, because of the mouse lag! And this mouse lag could be seen in games like Dues Ex: Human Revolution, Call of duty, Hitman Absolution, Metro 2033 , Tomb Raider and S.T.A.L.K.E.R: Call of Pripyat. Some Reddit users say that this lag is due to the New DPI Framework incorporated in the Operating System. We were long waiting for the fix from Microsoft! And here it is.
Download and install the KB2908279 patch manually from Microsoft. As a result you will get a compatibility flag in windows and this flag will be applied to games like Call of Duty series, Deus Ex: Human Revolution, Counter Strike series, Hitman Absolution and other popular games.
