My Gyro Works On The Switch But Does Nothing In PC Games

The data is reaching your PC, as your test proves, and the gap is entirely in what games choose to read.

PC games overwhelmingly read controllers through XInput, which has no concept of a gyroscope. It defines buttons, triggers and two sticks, and that is all. So a game using XInput will never see your gyro no matter how perfectly the controller reports it, and that is not something you can fix with a driver or a setting in the game. Only a small number of PC titles read gyro natively.

The standard solution, and it is a good one, is Steam Input's gyro-to-mouse conversion. Steam reads your controller's gyro directly, converts rotation into mouse movement, and hands the game mouse input, which essentially every game understands. The result is genuinely good: it is how most PC players use gyro aim, and in many cases it feels better than console gyro because you can tune sensitivity and the activation behaviour precisely.

The setting that matters most is how gyro activates. Always-on gyro is unusable for most people because every hand movement moves your aim. The usual configuration is to bind gyro activation to a button or to the trigger, so rotation only becomes mouse movement while you are aiming. That single choice is the difference between gyro feeling broken and feeling excellent, and it is the thing most people get wrong on their first attempt.

A few practicals. Add non-Steam games to Steam so they get the same treatment. Make sure the game is in mouse-and-keyboard mode rather than controller mode, since you are feeding it mouse input, and that occasionally means button prompts show keyboard icons. And calibrate the gyro first: if your controller has a bias offset, gyro-to-mouse will turn that into a slow constant drift of your aim, which is far more annoying than it is on a console.
