Lost Planet – Dual GPU
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.
Lost Planet throws a bit of a wrench in the discussion here; even though at 1600×1200 and 1920×1200 the scaling of the 9600 GT is impressive (about 88%!!) and the pair easily outperforms the single 9800 GTX and the dual-GPU single-card HD 3850 X2 something quirky happens at 2560×1600. Basically, NVIDIA’s performance at this resolution is so poor (on both the 9600 GT and the 9800 GTX) that even a near doubling of performance with the 9600 GT SLI setup can’t best what the AMD-based ASUS Radeon EAH3850 X2 1GB throws out there.
