Had a chance to put Fallout New Vegas through its paces with my new Alienware Aurora R3. All I can say is wow. My last PC was no slouch, but the thing that always killed New Vegas for me was the load times between areas, and the jerky frame rate that occurred for the first 20 or 30 seconds you were in a new area.
The Aurora gets rid of that. The longest load time I have experienced was about three seconds. Most areas transition so fast now that I don't even see the load screen pop up. There's no jerkiness as the textures load in a new area, and the animations on things like fire are much smoother. The lighting effects seem to stand out a bit better as well.
So far I'm impressed. Hopefully this Alienware will perform just as well in my other games. (Especially Brink!)
