This problem started with skyrim and now with fallout 3. from 1 day to the other any definition I chose low, medium, high or ultra they all look like crap, like they where set to low quality.
I've tried everything but the definition quality just does'nt want to change... anyone has any idea of what this might be about?

other games plays just fine, my laptop is a Alienware Mx17 with a 6900HD AMD RADEON
