MSI mode is a Windows feature that allows hardware devices like graphics cards to communicate with the CPU more efficiently. Introduced with PCIe 2.2 and Windows Vista, it uses memory-mapped interrupts instead of physical lines to reduce latency. While it can improve consistency and reduce input lag on older systems, it does not increase frame rates and can cause instability if forced on hardware where manufacturers have disabled it by default. Modern drivers for cards like the RTX 5090 typically enable MSI by default, and overriding a manufacturer's decision to disable it carries risks of crashes and driver timeouts. AI
