Graphics card memory limitations?
In the examples below, when I say maxed, its as high as I could turn it up with my machine (and I assume my 4850 (512mb) limits this).
Machine is a Q6600@stock, 4850@775/1006(I think), 4GB DDR2, in a P5Q PRO.
Resolution is 1600x1200. CPU & GPU loadlines are taken from completely random fast burns in a 'vette around the city, usually ending in an epic fender-bender
First up: auto configure for numbers and text options (higher, highest etc) maxed:

We then look at everything maxed:

Both CPU (average) & GPU core loading has dropped, but my FPS definitely suffered...
Core 1 is interesting, its loading has increased. Maybe the multi-threading isn't/can't break certain discrete tasks down across all cores?
It could be able to spread discrete tasks over the four cores, but that won't save you if one task/group of tasks allocated to one core is more than that core can handle (which would explain FPS drop (you are limited by that core), and a lower loading on other cores (other tasks are being 'held back' by that one)...
Or I could be missing something very obvious...
