FS9.cfg entries?

Chris Willis posted this question back in September, so I thought I'd ask again, now that so much more is known...;)There are several parameters in FS9.cfg that cannot be altered via the UI, including these, in the (Display) section:Auto_LOD=0LOD_Target_FPS=14Image_Quality=0Texture_Quality=3While descriptively named, I've had a difficult time figuring out exaclty what these do, if anything. Particularly Auto_LOD. Setting it to 1 doesn't seem to do anything for me...does anyone know if it works in FS9?And exactly what do the others do, such as both quality setting?Thanks!sg
