I have been playing it a bit since the legacy art port, and I have noticed its quite a bit faster. Not that you can move forward faster, but that you can turn MUCH faster. For me in 2d there was always the little lag that occurred when you tried to turn and keep running, that doesn't exist in KR. Its also very nice for crafting. I've yet to try anything very active with it, such as pvm or anything, but it seems like its really coming along. Now that I don't have to look at the awful KR item art I might actually consider playing it more often. Most of my problems with it are involved with the crappy parts of the interface. The items being too small, the free form backpack having issues about where items land where you drop them. The annoying avatar art is something I can deal with, so are the weird shadow issues. They aren't so distracting that they draw my attention away too much. Anyone play KR a lot? Have much luck with pvm?
