S.T.A.L.K.E.R.: Shadow of Chernobyl
The game doesn’t support FSAA when you enable the dynamic lighting model, but loses much of its visual appeal with the static model. So, we benchmarked the cards in S.T.A.L.K.E.R. using anisotropic filtering only.
The Radeon HD 2900 XT fails this test completely. You can’t play normally using the dynamic lighting model even at 1280x1024. The new card being slower than the Radeon X1950 XTX, the reason is surely somewhere in the Catalyst driver rather than in the R600 GPU proper. On the other hand, recalling that the GeForce 8800 GTS 320MB often loses to graphics cards with 256MB of memory on board and that the developer hasn’t yet enabled FSAA for the dynamic lighting (the reason why we have to test S.T.A.L.K.E.R. with anisotropic filtering alone), we can suspect some defects in the game itself, not only in ATI’s driver. Anyway, you shouldn’t play S.T.A.L.K.E.R. on a Radeon HD 2900 XT 512MB as yet.
