My Dualshock 4 works great with InputMapper besides the right input on the left stick. I noticed this when playing Brawhalla and Dirt Showdown. Pushing the left stick to the right only works about 5% of the time. I haven't figured out what makes it work the 5% of the time. Any ideas? By the way, I don't encounter this problem when using the Dualshock 4 with the PS4 itself.
