Half-Life 2 CPU Shootout: AMD versus Intel@ 2004/11/22
The tests at 800x600 employ low model detail, low texture detail, no anti-aliasing, no bilinear filtering, simple water reflections, low shader detail, low shadow detail, and the DirectX 9.0 code path.
At 1280x1024, those settings rise to medium model detail, medium texture detail, 2x anti-aliasing, 2x anisotropic filtering, world reflective water detail, high shader detail, high shadow detail, and again, the DirectX 9.0 code path.
Then, 1600x1200 steps in to represent Half-Life 2 at its pinnacle. Here you’ll find high model detail, high texture detail, 4x anti-aliasing, 16x anisotropic filtering, world reflective water detail, high shader detail, high shadow detail, and naturally, DirectX 9.0.
