I have been working on some basic cartography for a fantasy world I am creating, and ArcMap 10.4 was being slow on editing some of the large island polygons I am creating. I figured that as all I am doing is basic editing I would try ArcGIS Pro for speed and to be able to use my 16 gb of RAM. I love how responsive the program is generally, but editing is frustrating. When I click on "Move" to move a feature, for example, the program doesn't allow me to actually move or rotate any feature until several minutes of the mouse cursor with the spinning wheel. All I have is a basic polygon layer for islands and a basemap. Why is it being so slow?
It's in a File Geodatabase. They do have large amounts of vertices because several of the polygons are the size of large islands several hundreds of miles across. I turned off Map Topology and things seem to have sped up a lot -- I bet that's the problem!
