Microsoft has distributed an emergency fix to squash a bug that caused PC gamers to experience frame rate issues that were the driving force behind the latest Windows 10 update

The issue arose from a cumulative update pushed to Windows 10, where users reported lower-than-expected frame rates and stuttering in games Some users resolved the issue by rolling back the update to an older version, but this is not a long-term solution

However, to resolve this issue, Microsoft noted the following in the Known Issues and Notifications section of its support site: "A small number of users have reported that after installing KB5000842 or later updates, game performance is slower than expected after installing KB5000842 or later updates Most users affected by this issue run games in full-screen or borderless window mode and use two or more monitors

"This issue will be resolved using Known Issue Rollback (KIR) It may take up to 24 hours for this issue to be automatically reflected on consumer and unmanaged business devices Rebooting the device may cause the resolution to be applied to the device sooner

You may need to patiently wait for the fix to be applied to your Windows 10 desktop or laptop However, make sure Windows Update is turned on

The frame rate bug and issue arose from two recent security updates to Windows 10 Specifically, the two updates are attributed to Knowledge Base numbers KB5001330 and KB5001337

Reddit posters have complained that there seem to be numerous issues affecting these updates; KB5001330 seems to be getting the most flak, while users with VSync enabled seem to be taking a big hit in performance

Interestingly, Nvidia previously noted that KB5000842, which Microsoft pushed to users on March 29, also has problems Specifically, on a computer capable of achieving 180 frames per second in Overwatch, performance dropped to 40-45 fps when VSync was turned on The goal is 60 fps, which should be easily achievable Of course, one can also stop using VSync and endure severe screen tearing

Tech site NextV also reported that installing two updates, KB5001330 and KB5001337, may cause some users to blue screen with multiple error messages should), this could be a serious problem, so to be safe, you may want to consider not installing these updates until Microsoft's fixes are officially distributed

Using older versions of Windows is of course generally not a good idea, but if the updates make your PC much worse, then when Microsoft releases a new update that addresses these problems, take the chance If the update makes your PC much worse, it is advisable to take the chance and update when Microsoft releases a new update that addresses these issues
