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.
AMD’s HD 2900 XT doesn’t stand a chance in the single card tests and loses to both the 8800 GTX and 8800 GTS 640MB card pretty substantially.
The SLI performance on Lost Planet is pretty good, getting nearly 60% average frame rate gain by adding a second 8800 GTX card or a more impressive 81% gain with the 8800 GTS 640MB cards. The CrossFire setup with a pair of AMD HD 2900 XT cards does scale at about 43%, though I am disappointed to see the minimum frame rate only jump up a couple of ticks here — both of NVIDIA’s SLI setups nearly doubled them.
