Intel Skylake Adds ASTC Texture Compression, Open-Source Support Coming

S3TC remains the most common form of texture compression relied upon by video game developers and others, but it remains a legal mess for open-source graphics drivers. ETC2 texture compression isn't faced by legal issues but was only mandated by OpenGL ES 3.0 / OpenGL 4.3, which makes it less well adopted. Meanwhile, in looking forward to the future, ASTC is the royalty-free next-gen texture compression solution that's backed by the Khronos Group. Intel's forthcoming Skylake hardware will make ASTC a much more widespread reality.

Gallium3D's LLVMpipe Tacks On Another OpenGL 4 Extension

Most often when talking of new OpenGL 4 extensions in Mesa it tends to be regarding the Intel Mesa driver given they're the company investing the most into the Linux graphics stack, followed by the Radeon and Noveau drivers. However, this week in Mesa is some love to the fallback/debugging software rasterizers.
