The gamepad troubleshooting journey is a long one for XIV. I play on PC. I've gone through a Logitech f310, two Logitech f710s, one Steam controller, and finally settled on PS4 controller from Best Buy. Plug it into PC usb slot and never ever change usb slots for that controller. It's weird, but I think it's some Windows glitch. All the logitech controllers would make me run in one direction for 3-4 seconds longer than I intended, at random times. Steam controller worked but camera movement is horrendous. I even went as far as to buy new motherboard, GPU, CPU, and the problem followed. So by the time I bought the PS4 controller I established some rules for gamepad gaming on FFXIV. No wireless, straight cable to USB from gamepad, never change usb slot, don't install any third party drivers for PS4 controller, let Windows 10 do drivers on its own.
