I use the Steam Controller for games like Doom Eternal, Left 4 Dead 2, Spin Rhythm XD, The Finals, etc.

Using steam input is a requirement to get the most out of it.

This is my basic approach for most games.

• Mapping mouse to touchpad and adjusting sensitivity to 180
• Mapping mouse (beta) to gyro and adjusting sensitivity until 90 degree turn of the controller turns in game camera 675 degrees for first person/450 for third person
• Setting up a dpad modeshift on right touchpad click and inverting outer ring so I can set the touchoutput 5 different actions depending on if I click up, down, left, right, center as opposed to only a solitary single click action. If I need more I set up a chord so holding left grip shifts the same actions into another set of 5 inputs. I got for Dead Zone: 181919 and Outer Ring Binding Radius: 16750 when it comes to values in the new Steam Input.
• Setting movement to left pad and and setting an outer ring sprint bind on it and mapping crouch/slide/dash actions on click

I saved the template for gamepad bindings for games that support mixed input and full mouse and keyboard for ones I don't. So I don't have to go through the whole thing all the time. I just apply my template and then just switch the bindings around and adjust the sensitivity.

If you want to try out a config I have one uploaded for the Finals called "dualpad with gyro update..." Some changes you'll want to make to the settings is Mouse sensitivity to 20, mouse focal length sensitivity 106, swap ping and emote in game, change sprint and crouch to hold, and obviously turn off aim assist. Holding the right start buttons switches into an action set I use when playing light where left grip is crouch as opposed to a chord modifier like in the default and left pad click is for dashing and grappling. Default action set clicking the left pad is crouch/slide and left grip changing the right pad clicks to gadget switching.
