I guess it can be said with reasonable assurance that the mouse issues affecting some games on Windows 8.1 were rather widespread, because Microsoft rolled out a patch to fix the lag bug on the new operating system late last week.

The terrible mouse lag has made many games unplayable, both casual and AAA titles.

Redmond confirmed the issue a while back, while also providing tweaks and workarounds to the main executable files of the games in question and run them in compatibility mode. According to the company, some changes in the way Windows 8.1 handles mouse behavior messed things up:

“This issue occurs because Windows 8.1 introduced changes to mouse input processing for low latency interaction scenarios. Therefore, games respond to mouse inputs differently in Windows 8.1 than in previous versions of Windows.”

Anyway, now there is a fully working patch out that fixes the issue once and for all on both 32-bit and 64-bit machines. Microsoft has also revealed a list of some of the games that were affected. And it includes both single player and multiple components of some of the most popular titles around, like:

Call of Duty: Black Ops, Call of Duty: Black Ops II, Call of Duty: Ghosts, Counter Strike: Global Offensive, Counter Strike: Source, Deus Ex: Human Revolution, Hitman Absolution, Half-Life 2, Metro 2033, Portal and Tomb Raider.

Anyway, the patch is now available for download, interestingly ahead of this month’s Patch Tuesday cycle. You can take a look at the patch for x86 and x64 versions of Windows 8.1 at their respective links.
