the most detail scenery range and autogen range

Dear all,I am trying to work with fs9.cfg to set-up the best appeareance possibile.Still not able to set-up bigger range for visibility of the most detailed scenery/textures (not visibility itself but the visibility of the best detail one).The same problem is with autogen. the objects are just appearing at about 4 miles in front of me. Is it possible to set-up somehow bigger distance ? many thanks for adviceJM
