No, lossless. Lossy compression of textures has a much higher ratio.

Sounds strange, why not do this compression in DX9 as well if it's lossless?

Because its not in spec. Textures are just xxx by xxx bitmaps. Very easy to compress those.

Not in the spec? Still sounds strange. Compression alogritms are actually pretty complex and my PC sports a DX9 capable graphics card, but also sports a faster CPU for decoding than the Xenon is capable of. I see no reason why I would need a better GPU for my CPU to perform more efficient decoding.

Why would Xenon be decoding? The GPU decodes the textures and the texture compression is based upon the lowest level DX supported. DX11 is up to 10:1 compression but that will only be implemented on DX11 only code.
