Matteo Bruni (@Mystral) commented about dlls/d3dx9_36/tests/texture.c:
ok(desc.Format == D3DFMT_A8R8G8B8, "Unexpected texture format %#x.\n", desc.Format); skip("D3DFMT_DXT3 volume textures are not supported, skipping a test.\n"); }
- /* The lower texture levels are apparently generated by filtering the level 0 surface
* I.e. following levels from the file are ignored. */
I wonder how did I get to this bad conclusion at the time... Oh well.
