Originally developed by a community member known as mbk1969, the tool has seen steady improvements:
This guide will explain what Message Signaled Interrupts (MSI) are, how to safely download and use the utility, and how it can significantly improve your system's responsiveness. Understanding Interrupts: IRQ vs. MSI
Switching your critical hardware—especially your NVIDIA or AMD graphics card—to MSI mode offers several immediate performance upgrades:
Look at the user interface columns. You will see a list of your hardware, followed by a checkbox under the column, and an interrupt priority dropdown.
Ensure you download the utility from verified community hubs, back up your system before editing, and remember to re-apply the tweak after your next GPU driver update.
