If your games stutter on Windows 11 24H2 or 25H2 despite high FPS, you may have the dual GameInput bug. Windows installs two competing versions of the GameInput Service that fight over mouse and controller polling, causing constant micro-stutters.
This bug is nearly impossible to find by Googling — most gamers blame their hardware or drivers.
How to check and fix:
- Press Win+R, type 'services.msc', press Enter
- Scroll through the services list looking for TWO entries named 'GameInput Service' or 'Microsoft GameInput'
- If you see two entries, click each one and check the 'Path to executable' in the Properties
- One will point to an older X64 folder path — DISABLE that one (right-click > Properties > Startup Type > Disabled > Stop)
- Keep the newer one running
- Restart your PC and test — stuttering should be dramatically reduced
- You can also check via PowerShell: Get-Service | Where-Object {$_.DisplayName -like '*GameInput*'}
- This fix is instant and often eliminates the worst 1% low FPS spikes. It's a Windows bug that Microsoft hasn't fully patched yet.
