While most of us now the Unreal Engine 3 rin on Windows 8, it now runs something else. Unreal Engine 3 now runs on both Windows 8 and Windows RT, Epic has announced. This is certainly good for anyone looking at the upcoming line of Windows RT tablets.
Epic showcased the engine running on just such a tablet, the Asus Vivo Tab RT, which you can see in the video below. The demo in question is Epic Citadel, which was first used to showcase UE3 on the iPhone back in 2010. Epic VP Mark Rein noted that this is the full Unreal Engine 3, using the “full DirectX 9 pipeline, with shaders and materials,” and not a “modified mobile version”
