Sets DragFullWindows = 0 under HKCU\Control Panel\Desktop. Instead of re-rendering a window's full contents every frame as you drag it around, Windows draws just a lightweight outline and snaps the contents into place on drop. Noticeably smoother window dragging on integrated/weak GPUs or when dragging large app windows. Takes effect on next sign-in. Reversible.
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.
