Hi, I can increase the limit, but first, you should try adjusting the lens true fov setting in the advanced video settings. That might be the better setting to adjust, because it's most likely an FOV mismatch.

You're right. The reason why I ask for the front setting is that it gives me slider, thumstick control using VR controller. I can find sweet spot with the controller easily but when I find what setting works best, I am going to lose it as soon as I touch another UI (being overwritten with the internal limit -0.75) and I need to find True FOV which is in different dimension.
