The problem with the NVIDIA 7600 is that is only support 1024 uniforms.

glxinfo -l:

    GL_MAX_VERTEX_UNIFORM_COMPONENTS_ARB = 1024

That means gl_info->vs_glsl_constantsF is 256. And in dlls/wined3d/directx.c
max_vshader_constantsF is then set to

    gl_info->vs_glsl_constantsF - (MAX_CONST_B / 4) - MAX_CONST_I - 1;

which is then 235, resulting in

    uniform vec4 VC[235];

in the shader code. But it seems Apocrypha needs more uniforms. Since i didn't
see any reference to VI and VB in the shader code I changed MAX_CONST_B and
MAX_CONST_I to 0 and recompiled wine. After that the models were rendered and
the overall graphics didn't look bad. There were some miner graphics bugs, but
the game worked.

Looks like the TODO in dlls/wined3d/wined3d_private.h needs to be done for EVE:

    TODO: Make this dynamic, based on shader limits
