I've recently bought Dead Money. While New Vegas runs very nice while I'm in the Mojave (constant 60fps), I have frequent drops in fps while playing Dead Money.
It seems that in certain areas in Dead Money, my framerate goes down a lot.
Did anyone else notice that DM has significantly higher demands on your hardware?
My system:
Phenom II 965 @3,4Ghz
4 Gigs of ram
GTX460 1GB
Win7 64bit
