The high quality settings reduced performance a little more and of course the GeForce 6600GT, 7600GT and Radeon X1650 Pro were unable to deliver playable performance. The Radeon X1950 Pro and GeForce 7900GS were again limited to 1024x768. The GeForce 8800 GTS and GTX were again very impressive, delivering playable performance at 1600x1200. However, it is scary to note that the worlds fastest graphics card only just managed to deliver playable performance at 1600x1200 in Supreme Commander!
