Under our more demanding foliage testing, the Radeon HD 2900 XT is able to pull closer to the GeForce 8800 GTS 640MB, actually overtaking the stock card by 1600x1200, but it’s not quite able to outpace the factory overclocked e-GeForce 8800 GTS 640MB ACS3. We have a strong suspicion that AMD’s got a lot more driver work to do when it comes to optimizing performance for this game though, as the results we’re seeing here just don’t correspond to what we expected.
