BEFORE

I used to import houses as mdl with this normal mapping shader assigned http://www.opserver.de/wiki/index.php/Normalmapping_Shader_With_full_specmap_support
And mixed with the shade-c the framerate was still pretty good.

Although being mdl they couldn't cast pre-rendered shadows.

NOW

I've converted those houses to meshes from the import fbx that wed has. I have pre-rendered shadows so I gain framerate, but i can't use the previous normal mapping shader anymore since there's no material defined in it.
Therefore I'm assigning a template shader which is the material mtl_bump but with this shader and shade-c my framerate drops down to a low again.

When i say shade-c i'm talking about hdr,depth of field, reflection and refraction.

I don't think i can be more specific then this.

Any solutions? Any other simpler normal mapping shader that doesn't go in conflict with shade-c?
