Logitech F710 Wireless Gamepad DX mode vibration

[12GaugeRabbit]

The Logitech F710 Wireless Gamepad has two modes, in Xinput and Dinput modes. When configuring vibration in Xinput mode, I can set up in Motor L and Motor R. but when I switch to Dinput mode, and in the vibration options, there are selections for Constant, Ramp, Sine, Square, Sawtooth and Triangle. I seem to not understand all those vibration options in the menu. Any recommendations for vibration?

Those DirectInput effect types are intended for use with actual "force feedback" devices. (joysticks/wheels)
Your drivers will probably map these effects to "something" but the names "Constant", "Ramp" et al. mean basically nothing in your situation.
Use "XInput".
