Epic Games have revealed and demonstrated their popular game engine technology running on yet another new platform, Microsoft's tablet-centric, ARM processor-specific version of Windows 8, the oddly-named Windows RT.

A blog over on the official nvidia site describes the presentation, which was part of an ASUS press conference that demonstrated the Epic Citadel demo running on the manufacturer's new Tegra-powered ASUS Viva Tab RT.

“The Unreal Engine 3-powered ‘Epic Citadel’ demonstration for Windows RT tablets implements the 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.”

A trailer from the presentation can be seen below, and Epic notes that Unreal Engine 3 licensees can now access the Windows RT code at the Unreal Developer Network, paving the way for developers to include Win RT support in any upcoming UE3-powered titles.
