If you are facing Windows 11 gaming lag after update, you are not alone. Many gamers notice that after installing a new Windows 11 update, their games start lagging, stuttering, or dropping FPS suddenly. Games that were running smoothly before the update begin to feel slow, unresponsive, or choppy.
This situation becomes frustrating because updates are supposed to improve performance, not break it. In reality, Windows 11 gaming lag after update usually happens due to system-level changes, driver conflicts, background processes, or new settings enabled automatically after the update. I personally experienced gaming lag after a Windows update, and fixing it required more than just restarting the PC.
In this guide, you will learn how to fix Windows 11 gaming lag after update using practical, safe, and proven methods that work in 2025.
Why Does Windows 11 Lag After an Update While Gaming?
Before fixing the issue, it is important to understand why Windows 11 gaming lag after update happens. Windows updates often change system files, power settings, background services, and driver compatibility. Even small changes can affect how games use CPU, GPU, and RAM.
Another reason is that Windows updates sometimes reset important performance settings. Power mode may switch back to balanced, background apps may get enabled again, and new services may start running automatically. These changes increase system load while gaming.
Graphics drivers can also conflict with new Windows updates. If the GPU driver is outdated or not optimized for the latest update, games may start stuttering or lagging heavily.
Windows 11 Gaming Lag After Update – Step-by-Step Fixes
Follow these fixes in order. You do not need to apply all of them at once.
Restart and Check Background Activity
After a Windows update, many background processes run silently to complete setup tasks. This can cause Windows 11 gaming lag after update.
Restart your PC once or twice and open Task Manager to check CPU and disk usage. If background processes are consuming high resources, wait until they settle before gaming.
Change Power Mode to High Performance
Windows updates often reset power settings, which limits hardware performance.
Go to Control Panel → Power Options and select High Performance. This allows your CPU and GPU to run at full capacity and helps reduce gaming lag.
Enable Game Mode Again
Sometimes Windows updates turn off Game Mode automatically.
Open Settings → Gaming → Game Mode and make sure it is enabled. Game Mode helps reduce background activity while gaming and improves stability.
Update or Reinstall Graphics Drivers
Outdated drivers are one of the biggest reasons for Windows 11 gaming lag after update.
Download the latest GPU drivers directly from NVIDIA, AMD, or Intel official websites. If lag started immediately after updating Windows, performing a clean driver installation can fix the issue.
Disable Background Apps After Update
Windows updates often re-enable apps that run in the background.
Open Settings → Apps → Installed Apps and restrict background permissions for apps you do not need. This reduces CPU and RAM usage while gaming.
Turn Off Windows Update Delivery Optimization
Delivery Optimization uses internet and system resources in the background.
Go to Settings → Windows Update → Advanced options → Delivery Optimization and turn it off. This helps reduce lag and network spikes during gaming.
Reduce Visual Effects in Windows 11
Visual effects may get reset after updates.
Search for Performance, open Adjust the appearance and performance of Windows, and disable unnecessary animations and transparency. This makes Windows 11 more responsive for gaming.
Check for Disk Usage Spikes
After updates, Windows may run indexing or cleanup tasks.
Open Task Manager and check disk usage. If disk usage stays high, allow the system to finish background tasks before gaming.
Advanced Fixes for Windows 11 Gaming Lag After Update
If basic fixes do not help, these advanced steps can further reduce lag.
Roll Back Problematic Windows Update
Some Windows updates cause performance issues for gamers.
Go to Settings → Windows Update → Update history → Uninstall updates and remove the most recent update if lag started immediately after installing it.

Disable Xbox Game Bar and Overlays
Xbox Game Bar and overlays can cause FPS drops.
Go to Settings → Gaming → Xbox Game Bar and turn it off if you do not use it. Disable other overlays like Discord or GPU overlays if possible.
Set Game Priority to High
While the game is running, open Task Manager, right-click the game process, and set priority to High. This ensures the game gets more system resources.
Common Mistakes That Make Gaming Lag Worse After Updates
Many users install random “PC optimizer” tools after facing lag. These tools often increase background load and make Windows 11 gaming lag after update even worse.
Another mistake is running multiple launchers, screen recorders, and monitoring tools together. These consume CPU and GPU resources continuously.
