My Wii Remote/Wii MotionPlus reacts slowly…
Is the problem with my Wii Remote or Wii MotionPlus?
To find out if the problem is with your Wii MotionPlus, first disconnect the attachment from your Wii Remote and try playing your Wii as normal.
If your Wii Remote is still slow to react, please see I'm having problems with my cursor or My Wii Remote isn’t responding correctly...
If your Wii Remote responds as normal, it’s likely your Wii MotionPlus will need to be fixed.
Could it be anything else?
Depending on your TV, the signal could take a while to be displayed. Please see My video or audio is delayed… for further information.
