I am not sure why. When I program M-buttons (M1-M6) in the Razer app, they do not work in BO7 at all.
I have uninstalled and reinstalled the app. I have removed and added the button mapping selections multiple times.
The standard button mapping works fine for the game but not the others. When I press the buttons, my character seems to move slower, and moves normally when the buttons are released.
Any help is appreciated.
