This game received Tobii eye tracking sometime in April according to Steam.

Does anyone know if the GOG version got the Tobii eye tracking update as well? Just got this through connect. When i can i'm going to download both versions and try to verify if it does or not myself, but i just thought i'd ask in the meantime in case anyone here already knew.
There's tobii files in the game directory but I haven't seen anything in the games menus.
