Disable Fullscreen Optimizations
Some games on Windows suffer from FPS stuttering or input lag because of Fullscreen Optimizations. Disabling this feature forces the game to run in classic fullscreen mode instead of Windows' hybrid fullscreen/borderless mode, which can reduce frame stuttering, reduce input delay, and improve overall performance stability.
This solution is safe and can be easily reversed if needed.
0 of 7 steps done
- Go to the game's executable file (.exe) - Open the folder where the game is installed (usually C:\Program Files or inside Steam/Epic folder), or right-click the game shortcut and select Open file location
- Right-click the main game file (.exe) and click Properties
- Go to the Compatibility tab at the top
- Check the box: Disable fullscreen optimizations ✅ - This prevents Windows from applying its fullscreen optimization layer
- (Optional) Also check: Run this program as an administrator ✅ - This sometimes helps with permission issues and anti-cheat systems
- Click Apply, then OK to close the window
- Restart the game and test if FPS stuttering or input lag has improved
This fix doesn't work for every single game, but it's one of the easiest and most recommended steps to try when you experience FPS stuttering or input delay on Windows.
