Two months ago reports surfaced around the web that the Wii u’s framerate drops to 30 fps when playing with two Gamepads. Naturally most gamers were not exactly thrilled by this.
Well fret not fellow gamers it seems like this issue has been resolved. According to a NeoGAF member , developers are definitely becoming more and more familiar with the Wii U, and have apparently managed to increase the framerate of their Wii U projects, and found ways to enhance images, quality and effects of their games.
The same member also claims that the Wii U GamePad’s sound quality is surprisingly good.
