A balanced bundle for play-and-stream: Game Mode on, hardware GPU scheduling on, MMCSS SystemResponsiveness eased to 10 (leaves headroom for an encoder/voice), and Game Bar background capture off. Keeps OBS/voice smooth while gaming. Reverts to Windows defaults. Reboot recommended.
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.
