so your loading couple of KBs of data for a part you want to use, instead of several GBs of data of all the parts that go along with that one part? I think The division is doing something like this with there "no loading screens". where as you load up once and as you walk around the world it loads that sector you are in and caces the one you left. The only issues I have had with this are falling through the ground and 8 bit graphics for about 10 secs while everything calibrates.
