AMD BIOS Guide for the best latency


A lot of bios power saving features have been developed over the years that cause input lag and can be changed to reduce it. Other bios features can change game engine behavior effecting game output e.g. MOH Revived, in my experience, CPPC and CPPC-PC Disabled. So one configuration is not a blanket configuration for all games and does not cover all uses. These settings do not reflect the best settings but I have found that changing the listed settings has reduced latency in our game.
