Unreal Engine 3 (UE3) is the third version of Unreal Engine developed by Epic Games. Unreal Engine 3 was one of the first game engines to support multithreading. It used DirectX 9 as its baseline graphics API, simplifying its rendering code. The first games using UE3 were released at the end of 2006. It was succeeded by Unreal Engine 4.
