Lost Planet Performance and Directx 10
Is DX9 actually better in terms of performance to DX10?...yep

We have all been waiting for a PC video game to be released into retail with “native” DirectX 10 support. We all thought Crysis would be the first game to be delivered with this support, but it isn’t here yet unfortunately. Lost Planet: Extreme Condition, is now for sale and does boast DX10 support. Lost Planet’s roots are planted in the Xbox 360 but it has been ported over for PC gamers. There have been many upgrades made to the PC version of the game, namely DX10 functionality and at least one DX10-only feature. When you launch the game you can chose to enable DirectX 9 mode or DirectX 10 mode. The graphic upgrades from Xbox to PC include resolution support to 2560x1600, improved shadow quality, parallax occlusion normal mapping, image-based ambient occlusion, higher detail textures, the use of vertex texture fetch for the animation system and depth buffer reads improved for soft particles.
