Can You Use a PS3 Controller on Final Fantasy XI for PC?
No. You cannot use a PlayStation 3 controller natively with Final Fantasy XI on PC.
Why It Doesn't Work
No Native Support: The PC version was designed for keyboard/mouse and lacks drivers/configuration for PS3 controllers.
Unreliable Third-Party Tools: Wrapper software (MotioninJoy, SCP Toolkit) maps PS3 controllers to XInput but often suffers from compatibility issues, input lag, or failure with FFXI's specific input handling.
Recommended Alternatives
Xbox 360 / Xbox One Controllers: Use the XInput standard natively supported by Windows and FFXI—plug-and-play.
Keyboard and Mouse: The standard, fully optimized control method for the PC version.
For a stable experience, stick to officially supported input devices.
