Settings

This page documents all the settings in the Principia settings menu as they exist in the non-Android versions of the game.

Graphics

• Enable shadows

  Enables shadows. Recommended to restart the game afterwards to prevent graphical glitches from happening.

  Smooth (prettier) or sharp (faster) shadows.

• Shadow resolution

  The resolution the shadows are rendered at.
