You need to install some driver before you can use the controller right?
Yup. Use motionjoy driver (FREE) and apps. However, need to use xbox360 controller emulator as the option (inside motionjoy). Works like a charm no issue. btw, search the web for ps3 controller on pc, all poiting to motionjoy.
Yes, you need the internet to download and load the driver... but once. You need to load the driver before starting to play. Make sure to choose 360 xbox emulator, click enable and test vibrate and control panel to see if keys and analog are working. Just took like less than a minute to test it out. Haven't had any issues.
