Hey there!
I’m asking here as it wasn’t immediately clear from the QualitySettings documentation: which settings are actually relevant for a 2D game? As far as I know, anti-aliasing only applies 3D models, and if you don’t use particles, it’s quite literally only the VSync Count option that is relevant. Am I correct here?
Texture quality and shadow/lighting settings still apply.
Technically AA applies too, but only will be visible on sprites that have edges along their sprite bounds as calculated by a Sprite Renderer. If you take a solid-color rectangle sprite, rotate it to 45 degrees, and then toggle AA, you can see it taking effect, but it’s not going to be worth the overhead for most games.
