Wii Motion Plus input lag (Not dongle related)

[Choda]

I know that SMB doesn't make use of WMP. This is just the particular use case I've encountered. I do not believe that reverting to the windows Bluetooth stack would help as again, WiinMote works flawlessly. Lastly no, the face buttons lock up as well. The only that was present at the moment of the lockup repeats itself for the duration of the lockup (movement direction etc.)
