It doesn't show "Beta" anywhere, just straight up "Torment" - my old saves from the Beta showed up as "no longer supported/previous version". Eh, but I've only wandered in for about an hours game, so it's not like I've gotten that far into it to tell if it has more than the beta did...
Hm, and didn't the beta version on your Steam Library show up as "Torment - Beta Version" in the games list? I'm trying to remember now...
