Steam Deck

I'm trying to configure the gyro to help me aim. I've tried every configuration I can think of, or find online. I'm slamming head into a wall.

From what I can tell, the game now only accepts "steam controller" input. Which means the right joystick isn't actually a joystick, it's a weird virtual joystick, and there's some conversion going on. So when the old methods for getting gyro input are used, ie "as joystick" or "as mouse", the input is completely ignored by the game.

I've tried configuring a fresh controller configuration based on a standard controller, but then the game things I'm trying to use a keyboard and mouse and ignores all controller input.

Now, if I set gyro to "right stick (steam controller logo)", then suddenly the gyro starts affecting the right stick. But instead of being a relative input, as in when I pull the left trigger to aim, use the current gyro position as zero, and all relative movement should be applied to the stick. Instead it is an absolute value, with the movement being relative to the calibrated location of gravity down. So when I pull the left trigger, I immediately stare into the sky.

I think the solution to this is the "auto world tilt" option, but that is only available in the "gyro to joystick" configuration, which of course doesn't work.

Am I missing something completely obvious here? Can someone please guide me in the right direction? I miss gyro aim.

Thanks
