Can disabling power saving fix the steering lag on a Biostar B550MH during high-speed turns in Forza?

This was honestly ridiculous; I was getting screwed over by my motherboard in a racing game. Every time I tried a precision drift, the wheel felt like it was contemplating life instead of turning. Analysis showed the Biostar B550MH USB ports were jumping between 250Hz-500Hz polling rates in default power-save mode, causing input lag to swing between 18-35ms. I tried swapping every single rear port, but the lag persisted—a total waste of effort. I finally went into the BIOS, killed all USB power-saving options, and set the PCIe bus to High Performance. The latency panel now shows a locked 7-11ms response, and the car actually feels glued to my inputs. I did get some slight electrical whining from my peripherals after the change, but a shielded cable sorted it out. VRM temps are steady at 44-50℃. The system latency tool confirms the fingertip feedback is finally snappy.
