Now that r300g has progressed to the point where S3TC compression support is the last obstacle in making a lot of games work, I wonder if the work Corbin Simpson did at http://cgit.freedesktop.org/~csimpso...tc-by-the-book may be useful to alleviate the problem of needing an external library (which makes less complete the out-of-the-box experience, which is one main selling point of OS drivers).

Originally posted by MostAwesomeDude View PostIt would make it less necessary, certainly. It is maintained, but S3TC, by specification, doesn't necessarily work with multitexturing, and it's broken on many chipsets.
it is written that "Note: this page is no longer updated and the code no longer maintained."
