Got AC2 today(whoop) and also have AC1 for PC
You cant properly use a wireless 360 pad with the PC version, it doesnt recognise the triggers (views as an axis not buttons) and you get no vibration.
This is with a xbox 360 wireless pad taken from an xbox 360 using the wireless receiver for windows.
PLEASE FIX UBISOFT!
It may work with windows branded wireless 360 controller or the wired version of the controller (as all 3 are different in some way) Can anyone confirm as i dont have the other two(but will go buy one if it does work as intended!)
Like i say this is in both AC1 and AC2
