The ED vid I posted was made by Glowing Amraam and his gamma setting is at 1.6 and that looked bloody spectacular as per the vid footage. Was wondering if you adjusted as well as yours also looked marvelous.
In any event, three-quarters installed so I'll tinker later - always loved the eye-candy!
Also, you're running a NVidia card so disable MSAA as you have and run AA through the NVidia control panel settings - apparently helps a lot with FPS/jaggies.
There's a couple more titbits of tweaks floating about -I'll see if I can find them again and post them up.
Oh yes, word has it that trees are now collidable, yes? Goodness knows we have been waiting decades for that lol
