Help: Low FPS problem.

[Hellfire8]

Hi guys,

Just got a copy of the game and I love it. Game is brilliant but I am having a small problem.

I am playing on maximum @ 2048/1152 however my system specifications should easily cover it. my system spec's are bellow.

AMD Phenom II x6 running at 3.3ghz
8gig DDR3 dual channel 1600 Ram
Sapphiretech HD5850 Gfx card 2Gb DDR5 Core/765-Mem/1125

I get avg FPS of around 30-40 but if I zoom in it could drop as low as 10, however the game does not seem slow/laggy/have problems playing, I do not believe it is the card as the avg GPU load is only around 30%, it actually uses a higher load in the menu when setting a custom game up,

Help appreciated, cheers,
