Hi dasilvarsa, I had the same problem when I used cgpsmapper to compile a new TYP file from an xpm/text file. With the original TYP file the map rendered was much quicker. I then used online ati.land.cz to build my custom TYP file and it did not impact rendering at all. Now that ati.land.cz is no longer available, I am using TYPWiz4. It does not seem to have any impact on the speed of rendering. It seems that if the original TYP file is modified at bit level i.e. not re-compiled, there is no effect on rendering. Also, the header in the TYP file is different for different maps. Using the "wrong" one may impact on rendering. May I suggest you report this phenomena to the developer of your TYP editor.

I do not want to highjack your thread but, in the TYP files of the newer map sets I only find "extra labels data". No Polygon, Lines or Points info. Also the map displays with default appearance in MS & BC. How do these TYP files work? My custom TYP file has the desired effect.
