Half-Life 2: Episode 1

Performance numbers dropped insignificantly after activating high-quality AF on ATI hardware and disabling texture filtering simplifications on Nvidia’s hardware. While the gap between the rivals has generally shrunk, in the worst-case (for ATI) scenario the model X1950 XTX is still about 12% slower compared to the model 7950 GX2. Nevertheless, no matter which resolution is used, both high-end graphics cards deliver comfortable average performance with ATI hardware providing high-quality anisotropic filtering.

Prey

Both high-quality anisotropic filtering and disabling texture filtering optimizations lowered performance in Prey quite noticeably. Nevertheless, this does not change the whole picture: Nvidia’s GeForce 7950 GX2 is still ahead, even though performance of the Radeon X1950 XTX is definitely not dramatically low.
