The dual core Qualcomm Snapdragon in my HTC Evo 3D handles this game smoothly. No gameplay issues at all. One very minor incident involving text changed to white boxes, but it corrected itself when I snapped the screen cap to report it. Not real sure if that was a CPU issue or something with the Adreno 220 GPU. It wouldn't be the first game I've played that had issues with the GPU. Battleheart would crash until it was updated with support for it.
