Hello everyone,
Which setup “Normals & Tangents” is the best for the best FPS ?
Normals - Import,calculate,none ?
Tangens - Import,calculate,none ?
Which number of Smoothing Angle is the best ? 0 or 180 ?

None of these affect performance as far as I know.
Normals mean the way the vertices are oriented on the mesh. If you choose Import, the orientation set for the normals in your 3D package will determine their orientation. By using calculate, you can set the amount of smoothing for the normals. I usually just use Import for Normals and Calculate for Tangents. The smoothing angle doesn’t have an effect on performance, as far as I know. It just rotates the vertices so that they will look smoother, but really high values can cause glitches in lighting and textures. Really low values will make the mesh look like it’s made out of paper. I’d advice using Import on Normals, still.
Also, you might want to take a look at the mesh importer documentation.
