How to fix USB response delay on ASUS B760M TUF Gaming?
It's honestly ridiculous that my motherboard was sabotaging my combos; every time I went for a critical string, my character would just freeze or lag, which is a disaster in a fighter. I found that the USB ports on the ASUS B760M TUF were jumping between 500Hz and 1000Hz polling rates due to the default power-saving mode, causing input latency to swing from 8-22ms. I wasted way too much time swapping every single rear USB port, but the lag persisted. I finally went into the BIOS, nuked every single USB power-saving option, and set the PCIe bus management to High Performance. In the latency test panel, my response time was pinned at 4-7ms, and the moves finally felt snappy. I did notice a slight electrical hum from some peripherals during idle after disabling power saving, but a shielded cable fixed that. VRM temps are steady at 48-55℃. Exported all the latency logs to confirm the fix.
