yup, dual cores handling it nicely

u got a very similar system to mine, this is how im running it:
Model Detail - High
Buildings Detail - High
Land Detail - Low
Forests - Very High
Visual Effects - High
Texture Quality - Original
Damage Decal - High
Buildings Amount - Unlimited
Land Shading - Low
Grass - Off
Shadows - Off
Roads - On
AA Off, 1650 x 1080, SSAO OFF, Vsync On.
It did although run alot better with the last beta patch, i was also able to have shadows on. I still can now, but makes the new stutters alot more noticable.
i Love it
