DXT is a fixed ratio compression format designed for real-time hardware decompression of textures. While it’s also possible to encode DXT textures in real-time, the quality of the resulting images is far from the optimal. In this white paper we will overview a more expensive compression algorithm that produces high quality results and we will see how to implement it using CUDA to obtain much higher performance than the equivalent CPU implementation.
