The Unreal Engine 3 is a staple in many games both desktop and mobile today. With the immanent release of Windows 8 RT and Windows 8, ASUS showed off the engine running on their just announced Windows 8 tablets in both Pro and RT version.
The RT version is powered by a Tegra 3 chip, which is pretty popular these days in Android tablets. Both Epic and NVIDIA worked together to bring the engine to life on the upcoming Microsoft OS. Seeing the engine in action, it's great that the new OS will have support from Epic and perhaps we'll see some great games coming to Windows 8 RT.
