O cry me a river please. Windows 8.1 isn't even officially released why would amd waste there time? 13.8 is a beta driver and aimed at getting better smoother frame rate why would they make there work harder by adding a version of Os to the mix witch isn't even released? Amd do support windows 8.1 in version 13.6 so use that, the frame pacing drivers are a beta project and it's better to release on a Os the is more mature. It will come when the time is right, so just grow up and take it like a man.
