The water problem is indeed the same as the problem in the pixel shader test, 
but its not really related to pixel shaders(and yes, its bump mapping)

3Dmark2001 assigns the perturbation texture to sampler 0, 1 and 2, but the 
shader only reads from sampler 0. From sampler 1 and 2 it just uses the 
texture coordinates for the tex3m3 instructions. Sampler 0 has the u and v 
coordinates set to REPEAT, while sampler 1 and 2 have them set up to CLAMP 
coords outside 0.0 and 1.0 to 0.0 and 1.0 resp.

Now the problem is that in d3d the texture address mode is a per sampler 
setting, while in opengl it is a per texture setting. So sampler 0 is applied 
correctly, texture address mode set to repeat. When sampler 1 is set up 
afterwards, the address mode gets changed and set to clamp.
