Universal Distribution of Supercompressed GPU Textures!
KTX 2.0 adds support for Basis Universal supercompressed GPU textures. Developed by Binomial, this compression technology produces compact textures that can be efficiently transcoded to a variety of GPU compressed texture formats at run-time. Additionally, Khronos has released the KHR_texture_basisu extension that enables glTF to contain KTX 2.0 textures, resulting in universally distributable glTF assets that reduce download size and use natively supported texture formats to reduce GPU memory size and boost rendering speed on diverse devices and platforms.
Basis Universal provides two compression options. The ETC1S mode achieves significantly smaller transmission and GPU memory sizes than JPEG and PNG textures. The UASTC mode delivers higher quality textures than ETC1S while still achieving significant memory savings. Click the image below for higher resolution comparison.
