The NVIDIA Blog
has a video
of the Unreal Engine 3 running on a tablet under Windows RT and explaining how easily developers will be able to port their Windows and Xbox games. "The Unreal Engine 3-powered ‘Epic Citadel’ demonstration for Windows RT tablets implements our full DirectX 9 pipeline, with shaders and materials, all running beautifully on Tegra 3," said Mark Rein, vice president of Epic Games. "By porting the full engine as opposed to a modified mobile version, NVIDIA and Epic have made it easy for UE3 developers around the world to bring their best content to Windows RT, Windows 8, and NVIDIA’s Tegra 3 processor. Windows RT code is available to licensees from Epic now and we’re excited to see the great games they develop with it."
