The game runs very smoothly, even at high settings - however, when I open any of the larger UI elements (Diplomacy / Pirates window, but particularly the Research window), the framerate slows to an absolute crawl, and the mouse lags along with it.
The Research window is the worst by far - while there is noticeable slowdown with the other elements open, it's still not very difficult to click on what's needed. When the Research window is open, however, the framerate slows to something like one frame every 2 or 3 seconds, which makes selecting research items incredibly difficult. (It's a testament to how fun this game is that I keep at it, though!)
Here is my very abridged Dxdiag info (Full version sent to
