Slow game and black screen

[plutomaniac]

at your latest log I noticed these:

ERROR: Couldn't create SoundEntity 'react_scare6.snt'
ERROR: Couldn't create SoundEntity 'step_walk_generic_hard.snt'
ERROR: Couldn't create SoundEntity 'step_walk_generic_hard.snt'

I also saw you have v1.2 update installed as well as the latest Intel drivers. Try starting a new game, since you are at the very beginning, and see if that helps. That will only help if you updated the game to v1.2 after starting a new game.

Are you sure you have disabled or lowered to the bottom every graphic option inside the game? The launcher settings differ a little-bit from inside the game. Change the graphics to the lowest/disabled from inside the game and after a game restart try again.
