Right now, the RendererFeatTest doesn't work properly at all if I enable the S3TC extension with mesa git version, libdrm git version and libtxc_dxtn git version.
Not forcing the S3TC extension, the first test shows corruption on text (written on top left corner) while the i915 doesn't. All the test fails to show the background which is probably related to a texture not loaded because of missing S3TC extension or because of float textures not supported. SSAO (used in test 10) and Edge smooth (used in test 14) are disabled because of float textures not supported.
Should we report problem with RendererTestFeat in different bugs (listing each problem as a different bug, i.e. S3TC and Float Textures)?
Does S3TC work in other games? If not, it's a more general problem. (I'm not sure if S3TC works equally well for all r600g hardware, or only on Evergreen?)
Float textures only exist in marek's branch, and only for r300g, so it's probably a bit premature to file bugs about this. Amensia works without it, you're just missing out on a couple of effects.
