| - | Use <b>linestrip</b> instead of <b>line</b> to draw continues lines. | ||
| - | The drawing performance will be much better than using single lines as in the old sectorfile format. (much less data to process)<br>This means that if you export an old sectorfile to the new map format, you need to remove the duplicate <point> entries to improve performance. | ||
