How can you be so sure of that? I know the 3DS is a pretty powerful handheld, but this game was primarily designed for systems like the PS3, Xbox 360 and PlayStation Vita. Running it in a lower resolution on the Wii is one thing, but rendering it twice to create a 3D effect on the 3DS is something else entirely.It's not really the compression that I have a problem with as I know that will probably be fixed in the final version. It's the downgraded framerate (60FPS vs. 30FPS) when I know that the 3DS can handle 60FPS Origins.
But I do agree that the port seems to be worse than it could be. Disregarding the 30 fps, the game sometimes seems to loop sounds and stuff like that. It's really a shame, since the same game felt so fluid on the PS3.
