I have the same Problem. Always getting killed because everything takes to long to load/appear, makes my enemies invisible do I have to wait for everything to appear which makes me sittin duck. It sucks cuz when I'm in a hurry I fly very fast but the buildings need time to appear so I end up going thru them and sometimes even thru the ground, which gets me stuck :/ I'm just gonna uninstall and install it again hopefully it fixes the issue
