The Microsoft Surface is a Tegra 3 device, so its a logical step for NVIDIA to port their TegraZone technology to the Windows RT OS. The games at launch are Judge Dredd vs Zombies, Space Ark, Pinball FX 2, Reckless Racing Ultimate, Riptide GP, Soulcraft, Vendetta Online and Sprinkle. All of them are available from the Windows Store, but now you can procure their Tegra-3 optimised editions only from TegraZone. These versions feature enhanced graphics and effects such as physics, realistic clothing, dynamic lighting and particle effects. These extras are exclusive to the Tegra 3 hardware. Not that competing chips from Qualcomm and Apple will have a hard time with them, but NVIDIA played their cards better in regards to licensing technology. So, happy RT-gaming!
