Half-Life 2: Lost Coast
The performance of the Sapphire Toxic X1900 XTX is high enough, but this card is slower than the GeForce 7900 GTX. The gap is about 15% in 1024x768 and less than 10% in the higher display resolutions.
This tech demo seems to be using pixel shaders with multiple texture lookups. This is the only explanation of the lower performance of the R580-based cards that we can offer. They have a much higher shader execution speed compared with Nvidia’s flagship and feel much more confident at running many math1ematics-heavy shaders simultaneously.
Project: Snowblind is a rather simple game and uses simple visual effects. The Radeon X1900 family’s skills at processing complex shaders are not called for here, yet the Sapphire Toxic X1900 XTX still turned in an average result of 75fps in the highest resolution of the “eye candy” mode. The minimum performance is no lower than 64fps, so smooth and comfortable game experience is guaranteed even in the hardest scenes.
