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. This is the reason why we benchmarked the cards in S.T.A.L.K.E.R. using anisotropic filtering only.
The problem with the performance of the Radeon HD 2900 series in S.T.A.L.K.E.R. we noticed before still persists. Although the use of CrossFire mode brings about a considerable performance gain, the minimum of speed remains very low. The average frame rate is far from ideal, either, being higher than 40fps in 1600x1200 only.
This is one of the few cases when investing into two Radeon HD 2900 XT is not as rewarding as purchasing a single Nvidia GeForce 8800 Ultra.
