Ive cranked 3d separation to 5 by default, but there are like 2 places where object inspection is impossible to see at that strength, close 1 eye, crank it back to 1 or switch z3d/off for a moment (Forgot to try but I suspect edge peek toggling would solve it too)
5 feels best in the rest of the game and text is adjusted to be readable at that strenght.
Game stylistically is 2d but works so well in stereo, especially some forest scenes with big tree trunks.
