Until quantum computers become mainstream, we need to optimize our ScrollViews!
OSA can display large amounts of data efficiently through a List, Grid or Table, on any device.
Even if speed is not a concern for you, OSA still provides a plethora of shiny features, making it the ultimate replacement of Unity’s built-in Scroll View.
Create your own customized implementation or get started in just 1 minute via OSA wizard and continue expanding according to your needs, guided by the provided demos.
