Can anyone please explain what is the Target Resolution option available in iOS player settings?
There is Native, Auto (Best Performance), Auto (Best Quality), etc.
What exactly is Auto (Best Performance)? It reduces the resolution, but to what extent?
What’s Auto (Best Quality)? How is it different to Auto (Best Performance)?
The different settings scales the resolution, I believe the “Best performance” multiples the screen resolution by 0.75 and “Best Quality” keeps it at full resolution. You can tweak the multiplier manually if you search for “resMul” in your Xcode project. I remember getting issues with font rendering on thin typefaces when using it, so instead I decided to render the game at two resolutions, full res for the GUI and a render texture with lower resolution for the 3d world.
