Lost Planet (DirectX 10)
Lost Planet is a 1st or 3rd person shooter that was out originally on the Xbox 360 but then made the transition to a DX9/DX10 title for the PC this summer. Set in a frozen world where you have to kill the opposing aliens in order to sustain enough heat to stay alive, Lost Planet has some visually impressive settings that make it a good benchmark title.
There are few DX10 settings that you can enable to adjust for which shader path you would like to use that are only available on Vista when a DX10 card is detected.
The 8800 GT does very well in the Lost Planet game engine as it is able to once again show up the NV 8800 GTS 640MB card as well as the HD 2900 XT.
The SLI scaling with Lost Planet is also impressive: the dual 8800 GTs manage to run 75% faster than a single card and maintain an 83% faster minimum frame rate to boot! That translates into a much better overall gaming experience, even at 1600×1200.
