As you can see right there, the texture quality is crap in BFG. They say there is no compression, but it's staring us in the face.
Well they didn't say there was no compression, they said the textures look virtually identical.
The idea of compression does bother me alot. In RAGE they said the uncompressed textures wouldn't help because they weren't more clear, but they were wrong, the uncompressed textures look alot better. Why? Because they don't have the huge blocks all over that the compressed ones do. So yeah, compression is a nice tradeoff to get framerate and reduce filesize, but I really don't think Doom3's textures need any compression, they are blurry enough as it is.
