    I'm having multiple Adressables with around 5 .png files that are rather large (1080x1080px), and I'm using these always separately in my scene. This means that they're never on the screen at the same time.

    Now I'm wondering if it is better to simply keep these files separate of each other, or slight scale them and eg. fit 4 of them into a SpriteAtlas for better(?) performance or other advantages.

    Hi @MardukCorp,

    The decision of having them separated or integrated on an atlas with a smaller resolution depends on multiple factors.

    Some of them are:
    • How much memory your game is using on the targeted lower-end device
    • How much quality is lost while making your images smaller
    • How frequent are the images used/swapped
    • How fast you would like to have the respective images switched
    Depends on the answers to these considerations you can make the right decision.


    Good luck with it!

    Hi @DiegoDePalacio, thank you for the details!

    The most important things are that the images would be swapped quite frequently and switching them should happen as quickly as possible.

    Ok, in that case, it's probably better to use a SpriteAtlas if the visual quality is good enough ;)
