Diamond Viper Radeon HD 2900 XT 1GB
|The highly anticipated game S.T.A.L.K.E.R. makes use of a proprietary DX9 game engine, dubbed "X-Ray" by its developers. It features an advanced DX9 renderer with Defferred Shading capabilities, which allows the engine to draw a vast amount of dynamic light sources with correct materials and light ‘feedback’. Becuase S.T.A.L.K.E.R. does not have a built-in benchmarking tool, we tested the game using FRAPS at resolutions of 1,280x1,024 through 2,560 x 1,600 with the in-game anti-aliasing and anisotropic filtering options set to their maximum values, and with full dynamic lighting enabled. We should also note that 'grass shadows' were disabled due to the dramatic slowdowns this feature causes during gameplay.|
The Viper Radeon HD 2900 XT 1GB card's larger and faster frame buffer gave it a marked advantage over the 512MB Radeon HD 2900 XT in S.T.A.L.K.E.R. and gave it the ability to hang just behind the reference GeForce 8800 GTS. However, the factory overclocked EVGA GeForece 8800 GTS and GeForce 8800 GTX were measurably faster at all resolutions.
