Windows 11 has landed on gamers' blacklist once again, this time with its January 2026 security update, KB5074109. Instead of fixing bugs and tightening security as expected, the update has become a quiet saboteur, leaving a wide range of Nvidia graphics cards running sluggishly and stuttering for no clear reason. If your expensive PC has suddenly started acting up over the past few weeks, the culprit may not be the hardware at all, but a serious problem in the operating system software.
The Faulty Windows 11 Update: Lower FPS and a Flickering Screen
It started when users on tech forums began reporting unstable systems all at once. At first, suspicion fell on Nvidia, since the company had also just released a new driver. The harsh reality turned out to be different: the operating system itself is the root cause. Reports from the gaming community show frame rate (FPS) drops of 15 to 20 frames while playing. In competitive games that demand precision, losing that many frames is effectively a death sentence, leaving gameplay choppy and frustrating.
It doesn't stop there. This troublesome update has also brought a string of annoying display glitches. Users complain of constant screen flickering, grainy shadows in games, and stray objects (artifacts) appearing on screen. Even Frame Generation, the most powerful weapon of the RTX 40 series cards, is malfunctioning. In the face of this backlash, an Nvidia moderator confirmed that the company is investigating the issue and advised users to uninstall the update.
Questions About Quality Testing and a Temporary Fix
This incident is more than an isolated technical bug. It raises big questions about the quality control process at Microsoft. The January 2026 patch contains more than 100 security fixes, but it also brings a dozen new problems: from crippling GPUs and breaking Remote Desktop connections to preventing Outlook from launching. Many theorize that Microsoft is leaning too heavily on artificial intelligence (AI) to write code (CEO Satya Nadella has said that AI writes up to 30% of the company's source code), and that this is hurting the stability of the operating system.
While waiting for an official fix (hopefully in February), Nvidia users have to fend for themselves. To fix the problem, go to Settings > Windows Update > Update history. Find KB5074109 there and select the Uninstall button. It is a temporary solution, but right now it is the most effective way to restore your graphics card's full performance. The advice for now: don't rush to install an update the moment you see the notification. Wait for feedback from the community first, so you don't turn your PC into a guinea pig.
