Texture encoders and decoders are often the most bandwidth intensive parts of a game and optimized encoding with Arm's ASTC encoder can provide a lot of benefit to runtime decoding.

In this article, we’ll get you up to speed on how ASTC differs from other texture codecs and why you should use it. Then, we’ll show you how you can integrate ASTC into your game or engine’s texture pipeline. Finally, we’ll demonstrate some quick benchmarks in both compression time and quality against common encoders used today.
