 ### The map performance is poor, how can I improve it?
 
 The performance mainly depends on number of visible elements and visible map area. The optimization strategies are: 
-* Toggle off all currently unused layers (esp. Relief Icons)
+* Toggle off all currently unused layers (especially Relief Icons)
 * Open the map in a small (about 960x540) window. The map will be the same, but it will work much faster as rendering area is smaller
-* Do not generate too big maps it you are facing performance problems
+* Close all unused tabs and applications (the performance depends on RAM and CPU)
+* Do not generate too big maps (use the Points number = 10K)
 
 ### My previously saved map is not working properly. What should I do?
 If there is no version conflict, please raise a defect. If your map is obsolete, you may either use an [appropriate version](https://github.com/Azgaar/Fantasy-Map-Generator/wiki/Changelog) of the Generator or re-create a map in a current version. The tool is under development and version conflicts are inevitable.
