Fixing command delay on Galax H310M Warrior D4 for Expeditions: Rome
It's honestly ridiculous that a strategy game is being ruined by my motherboard. Every time I clicked a critical command, my character just sat there like they were contemplating life. I found the Galax H310M Warrior USB ports were bouncing between 250Hz and 500Hz polling rates in power-save mode, causing input lag to swing between 15-30ms. I wasted time swapping every front panel port, but the lag persisted. I eventually went into the BIOS and nuked every single USB power-saving option, then set the PCIe bus to High Performance. The latency panel now shows a tight 6-10ms, and the controls feel instant. I did notice a slight electrical hum in some peripherals after the change, but a shielded cable sorted it out. VRM temps are a chill 42-48℃. Exported the latency logs for confirmation.
