okay sorry mein fehler!
im faq steht folgendes:
--SCREEN TURNS GRAY OR OBSCURES DISPLAY WHILE IN BULLET TIME.
Updating drivers will often solve this issue. If not, lower your in-game settings to "Medium" or lower.
--SCREEN TURNS BLACK, BROWN, OR ALTERNATES BETWEEN THE TWO WHILE THE SOUND PLAYS FINE.
Update your graphics drivers to solve this issue, or lower game settings to "Medium" to solve this problem.
also treiber updaten (wie schon gesagt) und dreh die performance auf Medium
weiterhin gibts schon einen patch (verbessert ladezeiten usw)
