A Fix for Windows 8.1 and Windows Server 2012 R2 Mouse Lag Issue

It has been reported that some people that are using Windows 8.1 still experiences the “Mouse Lag” issue since Windows 8. This issue started to rise  around after a month or two from the day of the release of the official Windows 8 Operating System. This issue is very noticeable for people who play games intensively on their Windows 8 and Windows 8.1 based computer.

Microsoft finally took a step  to release a fix for this issue. Yay! Unfortunately… This fix will not be installed automatically nor will be displayed in your Windows Update panel of updates.

People who installed the fix actually got their “Mouse Lag” issue fixed. I haven’t seen any negative feedback about it yet but who knows.

Microsoft noted that this update resolved the “Mouse Lag” issue in the following games:

• Call of Duty: Black Ops
• Call of Duty: Black Ops – Multiplayer
• Call of Duty: Black Ops II
• Call of Duty: Black Ops II – Multiplayer
• Call of Duty: Black Ops II – Zombies

According to Microsoft, “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.”
