Could someone explain the High DPI option to me? I am not well versed in monitor details.
Typically the game will render in double the resolution than what is set in the Width and Height settings, which will still be the logical resolution used in scripts and properties.
The reasoning behind rendering in double the set resolution is a mystery to me.
The reason is provided later in the document https://defold.com/manuals/adapting-graphics-to-screen-size/ : “This means that all measurements stay the same and any content that is rendered at 1x scale will look the same. But if you import high res images and scale them to 0.5x they will be high dpi on screen.” Essentially graphics will appear higher detail if scaled down without affecting the logical screen resolution.
