Wii U lag, on-screen & off-screen play.

hi everyone,

i have a wind waker hd wii u and never noticed a lag while playing it.

i then purchased from the eshop:

1) super mario bros.

2) punch out

3) NES Remix

ALL of these 3 games have a horrible lag.

should lag exist while playing off-creen on your gamepad?

i've spent countless quarters and time on super mario bros...and have been playing it more than any other game...and this virtual console version is UNPLAYABLE.

same thing for punch out...and NES REMIX.

is this something that can be fixed with a system update?
