My point is that Mario Kart Wii in multiplayer is not lightweight and it still runs fine in Surface Pro 3. You previously stated that only lightweight games would run in Surface Pro 3. I even dare to say that Super Mario Galaxy should be close to full speed in Surface Pro 3, especially in current development builds...
