Engine crashes while doing random "demanding" tasks like loading level/switching to landscape tool

Hmm, I thought that the false in TerminateOnOutOfMemory(D3DResult, false); meant the opposite, but I guess it’s an argument for something else. This would be odd. I have 16GB RAM, and watching task manager it seems to be okay when using Unreal. At the very least it shouldn’t crash if run out, no?
