Enables Message Signaled Interrupts (MSISupported = 1) on display adapters, which lets the GPU raise interrupts more efficiently than legacy line-based IRQs — often improves DPC latency and reduces micro-stutter. Applied per display device via its PnP instance. Reboot required. Reversible (revert sets MSISupported back to 0), though exact prior per-device state isn't snapshotted.
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.
