How to Fix FPS Drops and Stuttering in Games on Windows 11

Meta description: Resolve sudden FPS drops and in-game stutter on Windows 11 with targeted fixes, and use Kudu to improve gaming performance.

What Causes This?

FPS drops and stuttering in games on Windows 11 usually happen when your PC cannot deliver frames consistently. Common causes include outdated graphics drivers, background apps using CPU, RAM, or disk, overheating, poor power settings, and Windows features like overlays or Game Bar interfering with gameplay. In some cases, the problem is game-specific, but system-level issues are often the real reason performance suddenly becomes unstable.

Common Symptoms

• Smooth gameplay suddenly turns into short freezes or hitching
• FPS drops hard during combat, loading areas, or fast movement
• Audio crackles or desyncs when the game stutters
• GPU or CPU usage spikes while gaming
• Games run worse after a Windows update or driver change

How to Fix It Manually

1. Close background apps and check resource usage

   • Open Task Manager with Ctrl+Shift+Esc.
   • Click Processes and sort by CPU, Memory, and Disk usage.
   • End unnecessary apps like browsers, launchers, RGB tools, updaters, or recording software that are using a lot of resources.
   • If something keeps spiking usage, restart your PC and test the game again.

2. Update or reinstall your graphics driver

   • Right-click Start and select Device Manager.
   • Expand Display adapters, right-click your GPU, and choose Update driver.
   • For better results, download the latest driver directly from NVIDIA, AMD, or Intel instead of relying only on Windows.
   • If stuttering started after a recent driver update, open Device Manager > Display adapters > your GPU > Properties > Driver and click Roll Back Driver if available.

3. Set Windows to a high-performance power mode

   • Open Settings > System > Power & battery.
   • Under Power mode, select Best performance.
   • Then go to Settings > Gaming > Game Mode and make sure Game Mode is On.
   • If you use a laptop, plug it in before gaming. Battery mode often causes FPS drops.

4. Disable overlays and game recording features

   • Open Settings > Gaming > Xbox Game Bar and turn it Off if you do not use it.
   • Go to Settings > Gaming > Captures and turn off Record what happened.
   • Also disable overlays in apps like Discord, Steam, GeForce Experience, or AMD Software.
   • These overlays can cause frame pacing issues even when average FPS looks normal.

5. Check temperatures and reduce thermal throttling

   • Open your GPU software or a hardware monitor and watch CPU and GPU temperatures while gaming.
   • If temperatures are too high, clean dust from fans and vents, make sure fans are spinning properly, and improve airflow.
   • Overheating can lower clock speeds, which causes sudden stutter and unstable FPS.

6. Turn off unnecessary startup apps

   • Open Task Manager with Ctrl+Shift+Esc and click the Startup apps tab.
   • Disable non-essential items such as chat apps, launchers, sync tools, and helper utilities.
   • Restart your PC after making changes.
   • Too many startup apps can keep running in the background and hurt gaming performance.

7. Check game files and lower problem settings

   • In Steam, right-click the game, choose Properties > Installed Files > Verify integrity of game files.
   • Lower settings that often cause stutter first: ray tracing, shadows, texture streaming, and view distance.
   • If available, switch between fullscreen and borderless to see which runs better on your system.
