At the ASUS Vivo Tab RT press conference at IFA 2012 in Berlin, the tablet displayed the first-ever Unreal Engine 3 app on the Windows RT platform. 

 

The Unreal Engine 3 is the full PC version rather than an altered mobile app, which allows for the porting of PC and Xbox 360 games to Windows RT. Games on Windows RT can also be ported back to those other platforms. 

"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."

 

 

This is a huge boost for Windows, since it will likely further connect Microsoft devices. Windows 8 will be released October 26.
