When should I enable Combined Pedals?

Some driving games only work with Combined Pedals. In this mode, the pedals are reported as a single axis. Many arcade-style games are this way. When should I disable Combined Pedals? Disabling Combined Pedals reports the Accelerator as the z axis and the Brake as the r axis. This allows the pedals to be given separate characteristics in the game. Many racing simulation games support this mode.

How do I determine whether to change Combined Pedals in the Specific Game Settings window or in the Global Device Settings window?

Changes made in the Global Device Settings Window affect all profiles, applications, and the operating system. Changes in the Specific Game Settings window only affect the Profile that is active when you make the change.
