Half-Life: Lost Coast
We suspect Half-Life 2: Lost Coast uses shaders with multiple texture lookups, but there may be other improvements in the new Source engine that lead to the defeat of the Gigabyte Radeon X1900 XTX. Note that the results of the Radeon X1900 XTX do not improve much at the increased frequencies which may be indicative of its having too few TMUs. Currently, it is only the GeForce 7900 GTX that can provide a comfortable average performance in 1280x1024 with enabled FSAA in this tech demo.
It’s logical that the Gigabyte GeForce 7900 GTX wins this round: the game is simple and doesn’t use math1ematics-heavy shaders, so the Gigabyte Radeon X1900 XTX just has nothing to prove its muscle on. Anyway, the average performance of the R580-based card is 72fps in 1600x1200 whereas its min speed is a mere 6fps lower than that of the Gigabyte GeForce 7900 GTX. The cards are never slower than 60fps even in the hardest scenes of this game which means comfort for the gamer in every resolution.
Project: Snowblind was tested with the Fraps utility, but we used a cut-scene available in the game and are quite sure about the accuracy and repeatability of the results.
