thank youIf you want to ask BFG10K directly, you could just private message him.
cant fog table calculations be done per-pixel or per-vertex? wouldn't per pixel look better?I'm not even sure what you're asking. If you're asking what the different in-game fog settings do, then just try them. If you're asking if someone, somewhere, has implemented driver-forced fog that overrides that particular game's, then I very much doubt it.
