NVIDIA has announced that it has worked with Epic Games to port the Unreal Engine 3 to Windows 8 and Windows 8 RT (the version running on ARM architecture). This means that game developers using it will be able to target Windows 8 RT without too much trouble, if they account for the overall decrease in system and performance resources. Fortunately, that is very much manageable, so you can expect many Unreal game to show up soon.
If you are not a Windows person, you may have seen the Unreal Engine in action in iPad games like Infinity Blade (1 & 2). At the moment, the Unreal Engine 3 for Windows 8 RT will only run DirectX 9 rendering as it is the RT hardware platform limitation for now, but we’ve been told by several hardware manufacturers that 2013 would be the year of DirectX 11 for Windows 8 RT. At that point, we may see Unreal Engine 4 show up on Windows 8 RT.
The availability of Unreal Engine 3 to Windows 8 RT isn’t so surprising because this is an engine that was developed on Windows to begin with, and Windows 8 RT development is very close to regular Windows 8 development. Which Unreal-powered game would you like to see first on Windows 8 RT?
