I would like to point out, that using hardware mouse cursor does increase FPS quiete lot, when is cursor moving. This is definitely bug. When I have it ON, my FPS stays same(100) , but if I turn it OFF and moving my cursor all the time, FPS are going down to 15 !!
Another thing, if I move my cursor fast between two object(there and back all the time), which pop up info cards at the right bottom, FPS are going down by arround 10.
Also FPS are going down considerably, when I have got more cities on the screen, its not as sudden as for others... but it is bottleneck. Game with its graphics should be running absolutely flawlessly on my system, even with everything on MAX I should be running over 60FPS constantly.
Frame Limiter is not working, I always get more FPS then I set it to, which is annoying and also bugged.
Another thing.... I have no idea what Depth Of Field options does, and why its there, I can not tell difference between switching it on and off. It should blur vision over the further distance, which it does not.
Same goes for Max Texture Atlas size, what is it good for? I can set it to 1024x4096 max, if I try 1024x8192 it does not save, after restarting. Visual difference NONE.
Mip Map levels, same...I can not tell difference, what are they?
Shadow... Well, where are they? Except one tree and round shadow under characters... Where are all the shadows?
Softness(advanced lighting) Slider is not working, or if it does, difference is close to zero. I can set it to 0 make screen, and then put it on 100 make another screen, and can not tell difference.
I have got feeling, that engine is hugely unoptimized, or flawed, because, there is more problems, then just one. Performance, is going down, with so many things, and other things do not work at all.
I would post a DX diag, if there would be an easier way to do it, then over another website. Which you might want to consider in the future.
