It's too slow.
The system requirements are too high. The program installed for me (just!) but using it is a jumpy, laggy experience. For geospatial analysis and editing, you need something quick and snappy. Pro (1.4.1) just isn't that.
I'm not in a position in my office to request having more RAM, a new CPU, graphics card etc. so I'm stuck.
I've change all the display options for best performance and it's still too slow. Here is my Shift+E readout:
Pro needs moire customising options relating to performance vs quality (one example off the top of my head: remove the glowing outline fade after editing a shape. Instead just have it change instantly.)
ArcMap 10.4 runs fine, using the exact same datasets. Other software runs fine.
I get that ESRI are going for a more flashy and graphical interface, but at the cost of slower performance? That shouldn't be the case...
