I had my tab names disappear on me too. Once I started trying to play, selecting on the character creation screen was so laggy it was unplayable. (See video below) Alt tab DID work for me though. At around 1 minute in this highlight, I alt tab and come back no problem. http://www.twitch.tv/itsnotmyfault1/c/4936117 The level up screen was similarly laggy. Didn't try playing the game much, but after loading one of the NPC's was stuck halfway in the ground.
http://www.twitch.tv/itsnotmyfault1/c/4936117 Things were really laggy and unplayable for me. Not sure why. I'll try again later. My thoughts: it would be nice to have hover-over or other tooltips for the attributes when looking at the "race" tab. Especially as a first-time player, you'd want that to be quickly referencable, instead of having to go back after reading them on the attributes tab. Points not used during character creation seem to be lost forever. I didn't have any sounds when I was picking the difficulty and extra options.
