Both of those things are easily done with Gyro. You should try it out :D

I think you live in an alternate universe and also have never tried it

Gyro aim is very good and can easily compete with a mouse

Gyro is easily comparable to using a mouse

Is anyone else having issues with the game not allowing you to use any input except the left stick

But now it’s native! :D

No, foveated rendering doesn’t need the game to support it I use it all the time

It may be possible to run VR extremely well on the Steam Deck’s APU if Valve uses eye-tracked foveated rendering.

I don’t play any mobile games so I unfortunately don’t know any recommendations but if sandboxing an app that doesn’t respect your privacy sounds like a good solution to you, you could try shelter. Additionally, the Aurora Store can show you what permissions and trackers an android app on the Play Store uses.
