What happens when you press the button?

OVERDRIVE changes Windows visual effects, notifications, game capture and selected background settings. It disables selected OneDrive, Docker Desktop and Teams startup entries, switches to High Performance power and deletes old temp files.

Your existing setting values and previous power plan are saved locally. This preview has no undo button. Deleted temp files cannot be restored through the app. Running apps stay open.

Will it improve FPS?

That depends on your PC and game. Run the same game scene before and after to find out. Some Windows changes take effect after you sign out or restart.

The combined optimization has not been tested end to end on another PC. Read the source before running it if you want to see every change.
