Since neither Radeon X1800 XT/XL nor Radeon X1900 XT support texture sampling from vertex shaders, they use the SM2.0 rendering path to draw the water surface, while the GeForce 7800 family use SM3.0. So, ATI’s cards work under easier conditions, yet the performance ceiling is lower for them, probably because of their less efficient OpenGL driver. This problem, however, doesn’t prevent the Radeon X1900 XTX from delivering a playable frame rate everywhere except for 1600x1200 resolution with enabled FSAA and anisotropic filtering (the min speed is less than 25fps then).
