Hello there!
Getting single-digit fps mid-game on a small map with just 2 AI opponents.
When I start a new game the frame rate is close to 60, which then drops to 25-30 when I build the first city.
My rig:
qx9650@3Ghz (~45-65% load on one core, ~20-25% on all the others)
gtx580 (doesn't even switch to 3d mode, unless I enable 8x anisotropy)
8gb ddr2
Lowering settings doesn't seem to have any impact on performance.
Does the game not work well with older CPUs?
