Listen, I have an AMD Phenom 9750 and a GTX 460 SE and I get between 30 and 52 fps in the editor. It seems that whenever some people have trouble with a new game, other people tend to blame older graphics cards and processors. This is simply not always the case and is the reason why I haven't updated my system. Anyways here are my settings:
1920 x 1080 resolution HDR standard PIP standard terrain standard
1600 overall visibility anisotropic high Dynamic lights standard clouds standard
object 800, shadow 75 AA disabled Post processing low(simply because it makes the game ugly to me) shadows high
100 percent rendering resolution PPAA fxaa standard texture high particles high
vsync disabled Atoc disabled objects high
You really don't need new pc components every year to run new games properly. I learned that from wasting money years ago. Basically, my point is "please stop pointing the finger at old hardware every time and then maybe we can find solutions to some of these issues".
