we just tried g13, but find no trouble at all.
please check one thing in APP:
settings->global settings-> original controller deadzone=16.
this parameter shall be 16 by default.
And you will need to map G13's buttons and stick to the controller's buttons or sticks manually.
that would be clearer, and then Google does not correctly translate.
1. assigned the D-Pad to the G13 stick
2. turn on the game and check
3. D-Pad does not detect correctly or either side works randomly.
4. At the same time, the WASD buttons stop working.
5. I tilt the G13 stick in any direction, the WASD buttons work again, let go of the stick, WASD does not work again.
6. I switch the profile to another game and back, all the buttons work, I reject the stick and everything repeats as in step 5. I hope Google translated correctly and you understood my problem.
