If your network card and USB controller share an IRQ, a burst of network traffic can delay your mouse input or audio stream, leading to pops, clicks, or frame drops. The key advantages of MSI mode are: Check
Modifying system interrupts can cause stability issues if done incorrectly. Follow these steps carefully to ensure a safe configuration. 1. Run as Administrator
. By switching devices from legacy "line-based" interrupts to MSI mode, your hardware can communicate directly with the CPU without sharing interrupt lines, leading to smoother frame times and better responsiveness. Key Benefits of MSI Mode Reduced Latency Note of Caution This report is based on
