Performance Issues Reported
Users are saying they’ve experienced FPS drops of 15–20 in certain games after applying KB5074109. Additionally, they are facing issues like increased microstuttering, short black-screen freezes, and even occasional driver crashes when under heavy load. In many situations, the gaming experience only returns to normal after uninstalling the update or restoring a previous system image. Many sources, including MundoWin, Daily Game, and discussions in Nvidia GeForce Windows threads, highlight the same issue: while the update installs without a hitch, games that used to run smoothly now feel sluggish or less responsive on GeForce hardware.
No Official Acknowledgment
At this moment, Microsoft’s official documentation for KB5074109 does not mention any gaming performance issues, nor is there a specific hotfix targeting GeForce users. Nvidia has released a new Game Ready/hotfix driver that some gamers report is helpful, but the most common solution reported by users is to uninstall KB5074109 or revert to a previous restore point. After doing so, it is advised to pause Windows Update until a corrected build is made available by Microsoft. This situation leaves gamers with affected systems stuck between applying January’s security updates and regaining their full gaming performance.
