If you are a heavy PC gamer, you might not be happy with Microsoft's recent update to Windows 8.1
, depending on which games are on your hard drive and which mouse you own. Online reports have come in that claim updating to Windows 8.1 can make some games unplayable due to an "improvement" in handling DPI for multiple monitors.
In this case, according to a post on Reddit, the changes in the DPI framework have caused games that don't use Raw Input or DirectInput to get hit with a massive amount of mouse lag
. Among the games that are being affected by these problems are Deus Ex: Human Revolution, S.T.A.L.K.E.R.: Call of Prypiat, Metro 2033 and some games in Activision's Call of Duty series. It also seems to affect hardware that includes mice products with a high polling rate and high DPI.
