While it's not crazy fast, it's perfectly playable on my Thinkpad (Core2 Duo 2.4Ghz, 4GB RAM, Radeon 3650, 256 MB, DX11). I even put up almost all graphics settings to max. About the only time when rendering is really slow is in diplomacy view with dude that has fires in the background and air shimmering full-screen pixel shader (Aztecs?). Where it is noticeably slow is AI computing when finishing your turns (mostly towards the end of the game, when there are many units). But hey, it's turn based game, so it's not that bad :).
