The game loads fine, I can use mouse to start new game though no keyboard input seems successful.

My relevant specs:

* Asus Crosshair V Formula Z
* Windows 8.1 x64 standard Retail

For troubleshooting I've tried multiple keyboards both USB wirless, USB wired as well as an old IBM PS/2 I had lying around.

Tried in the main USB 2.0 ports that are recognised in UEFI fast boot / toggled UEFI fast boot.

Tried every USAB port.

Tried clean image of Windows 8.1 (haven't tried a fresh reinstall as of yet if can help it).

Mouse works fine, so does Xpadder, for some reason native keypoard input doesn't.
No response at all. Like say wasd or arrow keys
