I’m talking about the Engine itself, not the Launcher. The Launcher seems to have it’s own 15% CPU waste, even in the background, but often it calms down on it’s own. I, personally, just shut it down as soon as the Editor has loaded, to avoid any problems.
Of course, yet again, it’s another item Epic has made that seems to run up the CPU, and at the same 15%, even when nothing is happening on the screen at all. I know I’m not the only one who’s noticed what a bear UE4 can be on the CPU.
I can appreciate that the engine is powerful, and therefore needs to do alot, but when nothing at all is being done, even for hours at a time, there’s no need for it to be battering the CPU.
