If you don't mind that, go ahead and play on Dx9.
I have noticed that regardless of what DX version I am playing on, the lag experienced when you build up a lot of cities and items is almost the same, so I think it's more a processor issue than a GPU issue.
Because it does indeed look better with DX10, I am sticking to it
Hmmm.. I have 0 lag with DX 9.. smooth as butter. I will try updating my video drivers to the newest version (think i am still on a version from April... lol.). I would like to use DX 10 but it was a damn slide show for me, it has to be a driver issue.
What graphics settings are you using for DX10? I will use that as a starting point.
