Nope I don't use darkD3 or anything... And didn't mess with the gamma settings. I just noticed it sometimes detects the door and enters the cellar, other times it doesn't. Also sometimes he doesn't summon the fetish army, and sometimes he does. Should I mess with the computer lag settings? although it seems to run fine.
EDIT: I forgot to tell you I set most settings to minimal, for optimal performance, does that affect the way the bot works?
