 ### Custom map size
-Map is trying to fill the whole screen. If you want to change the map size, open the Generator in a separate window, change the window size to desired and re-generate the map. Or just set a desired resolution in "Options".

+### Performance tips
+The tips below can help if you are facing problems with performance on zooming and dragging:
+
+* Toggle off all currently unused layers (esp. 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
