Microsoft confirms KB5001330 causes the game performance to drop
According to Microsoft’s official support announcement, a problem with the recently released cumulative update KB5001330 may cause some game performance problems.
In fact, the above-mentioned problems have been discovered and reported by some users during the test period (KB5000842), but it does not seem to have received Microsoft’s attention, so the KB5001330 update also failed.
Microsoft did not confirm the problem until it was widely reported by some of the technology media a few days ago. However, Microsoft currently has no solution, so it can only uninstall the update.
“A small subset of users have reported lower than expected performance in games after installing this update. Most users affected by this issue are running games full screen or borderless windowed modes and using two or more monitors,” Microsoft noted.
A Microsoft investigation found that this problem mainly affects gamers with multiple monitors, and the game runs in full-screen or borderless windowed modes.
The fault here mainly refers to the problem of a significant drop in-game performance. Typical problems such as a significant drop in the frame rate of the game cause the game screen to freeze.
Some gamers may also encounter the problem that the game cannot be displayed normally on multiple screens after the game is started. Such problems are caused by the latest cumulative update.
This type of problem cannot be solved by game developers, so they can only wait for Microsoft to fix it, and Microsoft currently has no solution, so gamers can only uninstall the KB5001330 update.
In order to reduce the impact on users, Microsoft has currently activated the rollback function on the server-side, which was previously developed by Microsoft to respond to emergency situations at certain moments.
Microsoft stated in the support document that after the server starts the rollback function, the end-user will automatically delete the faulty update, and the whole process is automatic without user intervention.
For users, they may see a prompt that the system is being updated when the system is restarted. At this time, the system is not installing the update but executing the update uninstallation program.
In addition, the user can manually go to the control panel to manually delete the two faulty updates, delete and restart the computer, and then set to pause the update to restore the game performance.
