I can’t say that I agree with this. To be fair to the engine, you’re running below recommended specs… you need at least 8gb of RAM, not too mention that you’re using a laptop. If you think of the Kite demo as the modern day Crysis… only the high end computers are going to be able to run it at decent settings and framerates.
edit: I should mention that if you think this is bad, over my “weekend” I started a WM build process. 11.5gb of RAM used, and 67gb of page disk used. So the map took ~ 80gb of memory
