Ther is nothin inside ms ffb2 what can be or need to be programmed. Deadzone setting was software feature of old win 9x/2000 drivers, when PID part of HID spec was not implemented, but in windows XP and later PID driver is present so joystick drivers is not necessary.
Well. I spent some time and made my own FFB compatible usb joystick controller. And guess what - no stutter. I cant say what gives, i just emulated ms ffb2 on stm32 board
My controller is 1ms
