Message Signaled Interrupts (MSI) for system hardware. While the name suggests a direct link to the hardware manufacturer MSI (Micro-Star International), it is actually a community-developed utility designed to improve system responsiveness and reduce input latency by changing how devices like GPUs and USB controllers communicate with the CPU. The Quest for Lower Latency The story of MSI Utility V3 centers on the transition from older "line-based" interrupts to the more modern MSI protocol. In standard Windows configurations, many devices still use legacy signaling that can cause "contention" or delays when multiple components try to talk to the processor at once.
