Half-Life 2 Lost Coast
For this test, we used an internal demo recorded with Lost Coast to test Valve´s HDR, which uses a quite complex rendering format. It doesn’t maximize the additional capabilities of the GeForce 6, 7 and Radeon X1K, but runs with all DirectX 9 with MSAA.
Anisotropic filtering x16 was activated via the game.
The GeForce 7800 had great results. The 7800 GTX is ahead of the X1800 XT, and the GTX 512 and dual N7800 are in the lead. Is this the end of ATI´s supremacy in Half-Life 2?
With anti-aliasing, the X1800 XT is back in the game and ahead of the 7800 GTX. The GTX 512 is still far beyond reach, however. The X1800 XL is ahead of the 7800 GT and clearly above the X800 XT. This shows the benefits of ATI´s new architecture.
In HDR, the gaps widen. The 7800 GTX is back ahead of the X1800 XT and the 7800 GTX 512 and N7800GT Dual increase their advance. In 1920 x 1200, the GTX 512 is 40% faster than X1800 XT!
With anti-aliasing in addition to HDR, ATI is back in front of the 7800 GTX. The 7800 GTX 512 and N7800GT Dual, however, are still in the lead. The gain for ATI´s new architecture is close to 50%.
