I know you will be disappointed to see the results for 9400m, but remember that 320m is 1.8x faster than 9400m. The frames per second will be higher for the new one. Here are some informations about what computer, Windows OS, and Game setting I am using. Computer: MBP 13" late 2009, 2.26GHz, 160GB HDD, 2GB RAM, nVidia 9400m 256MB. Windows OS: Windows 7 Ultimate 64-bit (and 64-bit helps frame rate) Following pictures show different screen shots of gameplay including 'fps' on top left corner just below Menu (F10). I think you can tell which actions require more power (which brings down the fps). The game was smooth, playable. Massing Vikings, Thors, and Battlecruisers bring down to 24 fps. The zerg creep decreases fps by two.
