Still no dice. It's so weird. It's like there is a reticle in the background however the actual reticle (the circle) that is supposed to move with the left analogue stick, doesn't move. So you just have to guess where it is.
I've tried big picture mode, no big picture mode. Went into the steam settings in the upper left hand corner, enabled steam input for all the controllers, I have a generic PS4 style controller and an actual PS4 controller.
Only option I didn't see that you suggested was the "steam family view". Don't see that anywhere.
I don't know, this is puzzling.
I just went back and ran the game directly through steam, big picture mode on, and everything works as intended.
This has to be a GeForce now thing somehow.
