Civ 5 and very poor SLI performance

[Fuscusager]

hi all

i'm playing civ 5 on a 2x 295GTX QuadSLI setup, with latest nvidia driver. cpu 2600K, P67 MB and 8gb DDR3

DX10-11, in game settings all to high except shadows and fog of war on medium.
AA to 2X

at 1680x1050 or 1920x1080 the FPS are very low, 15-20-30 fps during standard gameplay on NORMAL map size.
only when i zoom in the map visual the framerate jump to 40 and sometime 50fps

i've tried Civ 5 on my notebook also, with a 2720QM and a 6970M as gpu, with same setting.
at 1920x1080 i've framerate over 40fps most the time, and often 60fps (60hz screen)

is that normal?
i really want to have higher fps on my deskop pc, with quadSLI setup!

Firaxis decided to not properly support the nVidia DX10.0 compliant cards under DX10/11 mode. Never mind that at the time Civ5 came out those were the most widespread gaming cards

Yes, this is normal

it's time to move on Civ 4 BTS...

i will play (maybe) Civ 5 when my 2 295gtx will be replaced for some DX11 cards.

thank you very much for the reply!
