Unreal's real strength has always been it's editor and tools. It's never been the most efficient when it comes to end product performance, but it's on the creation side where it shines.Unreal Engine in its stock form produces very unimpressive visuals and performance. Its only when Sony or Microsoft 1st party completely retool the rendering that it competes. Bespoke solutions such as Decima, ND engine, frostbite, RAGE etc produce far superior visuals and performance.
