observations :
The performances where better with memory set on Normal rather than Very High. I do not understand the behavior of this slider.
On very high settings i've got some ugly textures bugs
Fill rate seem not to be the worst perfomances impact.
I've got an overall poor score regarding to my specs. (Maybe the cpu is the achile's heel)
