Description Pavel Ondračka 2011-02-12 13:38:27 UTC 
When doing some other testing I noticed that there should be white fog near ground. I was quite sure it worked some time ago so I investigated this more. However this isn't regression its just that some configuration works and some not. The only one working configuration is Sanctuary v2.2 and shaders set to low, then it kinda works. Sanctuary version 2.3 with all shaders settings and 2.2 version with medium and high shaders quality are broken.
I've also tried RADEON_DEBUG=noopt and RADEON_NO_TCL=1 with no luck.

The fog is rendered correctly with the floating2 branch, and Unigine Sanctuary does use floating-point textures. This is what is printed during loading:

Mesa: User error: GL_INVALID_VALUE in glTexImage2D(internalFormat=GL_RGBA16F)

The game is clearly using float textures and doesn't check for the extension. Closing as NOT-OUR-BUG. Thanks for the info anyway.
