Lost Planet is a 3rd person shooter developed by Capcom and was originally an XboX 360 title until it was ported to the PC some time later. It uses the same engine as in other Capcom titles, such as “Dead Rising” and “Devil May Cry 4” known as MT Framework. It features the Havok physics engine and under Windows Vista and with a compatible video card, DirectX 10.
We not only use Lost Planet to determine the performance hit on Frames Per Second (FPS) when adding Anti Aliasing and Anistropic Filtering, but also the effects of changing the resolution from 1280*1024, to 1600*1200.
For all Vista tests, DX10 mode was used, and for XP DX9 was used.
High: 1600 x 1200, HDR High, 8QX AA, 16 x AF, all other settings at max.
Medium: 1280 x 720, HDR High, 8QX AA, 16 x AF, all other settings at max.
Low: 1280 x 720, HDR low, no AA, bilinear filtering, all other settings at max.
The 9800GT does pretty well here, staying almost level with the 4850 and 9800GTX at most settings, though it falls below playable FPS (25 IMO) at the highest settings.
