Sets TdrLevel = 3 (recover on timeout). This is the Windows default but some tweak scripts set it to 0 (disabled) which means a hung GPU bug-checks the system instead of recovering. Apply if you suspect a prior script broke this.
MaxTweaks applies this tweak with one click and snapshots your original setting first, so you can revert it cleanly at any time. A System Restore point is offered before batch changes, and every tweak links to its official source.
