Amnesia The Dark Descent Demo problem

[TheIdler]

I have similar problems as described in this thread, running a Sapphire Radeon X1950Pro.

First, black screen when starting the game, then very slowly brightening screen and subtitles appear. It takes about 30 seconds to render a single frame. Fixed by disabling the ImageTrail effect from the graphics options.

Second, the game hangs up completely when trying to open any menu in-game. I got tired after a 7 minute wait and killed the game with task manager.
