Unity has the ability to display in game statistics to help developers via the rendering statistics windows. This information shows information such as triangles and verts being rendered, audio level, fps, main and render thread operations time, etc.
I understand the importance of this information yet I'm still struggling to apply it into mobile phones. In this case I want to know how this information can be tied to mobile phones so that I can easily adjust my game to be suitable for low end phones as well as doing the opposite case.
For example, I want to make a big scene for the player, yet I need to keep an eye out on the triangles being drawn, however I don't know a numeric range to keep this triangles in between for the execution of the game.
¿Is there a way to calculate the maximum values that a phone can handle based on the phone's specs? ¿Should I just keep everything at the lowest, sacrificing graphics for better performance? ¿Or should I just do a trial and error on several phones until I find an equilibrium point between graphics and performance?
