Next Test: Lost Planet – DirectX 10

The DirectX 10 version of the Lost Planet demo is our next test to demonstrate the cards capabilities under DirectX 10, as all our previous tests have been for DirectX 9 applications.

There are two segments of the Lost Planet Demo benchmark, ‘Snow’ which is outside with a long view distance and lots of weather effects, explosions and close up character renderings, then there’s ‘Cave’ which is in a contained area filled with lots (and lots) of consistently slow moving characters.

The results above are quite surprising with the GeForce 8400GS blitzing the other two cards in the low resolution test, and staying even with the 2400XT in the higher resolutions. The 2400Pro also performs well, only slightly behind the other two cards in the higher resolutions. Considering the speed difference between the nVidia card and the ATI cards, it shows that the 8400GS is far more efficient under DirectX 10 than the others. This may simply be a driver issue for the ATI cards, or a flaw in their design, it’s really too early to tell. We will keep an eye out over the next few months to see if later drivers will make a difference to the Radeon 2400XT’s performance.
