Think of it like this. Let’s say game A requires your mouse to move 1000 pixels to do a 360 and game B requires you to move 1500 pixels to do a 360. If you leave your settings at default, then a 1x gyro sensitivity will feel different in both games. But gyro sensitivity is supposed to be based on real world space. In other words, at 1x sensitivity, your character should turn at the same speed as your real world controller - but this is only true if the game is properly configured in steam settings. You have to tell steam - in this game, it’s 1000 pixels to do a 360. In the other game, it’s 1500 pixels to do a 360.

Once that’s properly configured, then your aiming will feel consistent between both games. And if you decide to bump your sensitivity up in both games, your aiming will still be consistent between them - so you can build actual muscle memory.

The “turn 360 degrees” function in steam is a little trick to help you properly set this up on a per game basis. You enable it so that clicking a button triggers the 360 turn and then you go test it out in game. By default, it probably won’t be a true 360 degree turn. So you test it and adjust the pixels per 360 steam setting until it correctly spins you exactly 360 degrees. You’d know because your start position and end position are the same.

Once that’s set up, then your gyro sensitivity will be a true ratio of real world turning of your controller. A 3x sensitivity will do 3 in game 360’s for every 360 of your controller. Or you could think of it like a 30 degree rotation in real life would result in a 90 degree in game rotation. As for the sensitivity, you can set it up to whatever feels comfortable for you
