ARM-based Windows tablets are a couple of months off, and their gaming potential just got a nice boost from Epic. Unreal Engine 3, the basis for everything from Batman: Arkham City to Infinity Blade, has been ported to Windows RT. This isn’t some cut-down version of the engine, either. Nvidia’s blog post announcing the port makes clear that WinRT tablets are getting a full-fat PC implementation of the engine.
The embedded video below shows the Epic Citadel demo running on an Asus Vivo Tab RT tablet, which pairs a Tegra 3 processor with a 1366×768 display. According to the narrator, the frame rate is in the 35-40 FPS range.
Epic Vice President Mark Rein claims developers will be able to port their Unreal-based games to Windows RT with little trouble. The code is available to engine licensees already, and it will be interesting to see how many developers take advantage. Porting a game over to Windows RT is one thing, but adapting traditional control schemes to a touchscreen interface is another challenge entirely.
