Most NVIDIA cards doesn't support ARB_shader_texture_lod. Even most new. Even
with up-to-date drivers. And there is no standard demanding it to be the
requirement for shader model detection. So it is just working wrong. And opengl
does not follow Shader Model format. And it's not working as requirement,
because actually new Nvidia videocards are satisfying
gl_info->supported[EXT_GPU_SHADER4] condition, not ARB_shader_texture_lod. Even
7900gs is not passing this check. Only SM4 nvidia videocards could pass this
condition! I would so happy, if NV_vertex_program3 check were restored, so
nvidia 7 series cards shall be recognized by wine as SM3 compatible without
tricky manual patches.
