So, since i updated my Wii U recently i have been having no end of problems. Sure i can get back to the menus super quick, but the stability of the console has gone to shit. I get freezes when playing my games, and games like Need for speed which were silky smooth pre update, now have spluttering framerates. Lego City, which didnt have the best of framerates to begin with now runs like treacle. Is there going to be another update before the summer which will fix this, or can i default my console to pre update setting, as i didnt have any problems before. I have emailed Nintendo about this, hopefully i may hear something soon.

Not for me, if anything its even better, mine was freezing B.U ( before update) and now its fine.

The only problem I'm experiencing following the update is not being able to hear the awesome loading screen music for Nintendo Land. :(

Nope, no problems here, aside from the ones I've mentioned before (which actually occurred pre-update)

Highscore servers in Zen Pinball no longer work, Zen Studios is aware of the problem and working on it, but it takes time and that freaks me. I didn't play NFS since the update and I'm scared to try, since I heard on Miiverse and now here, that it lags. NFS shouldn't be a game that have lags.

No problems so far, getting back to the home screen has never been so quick

i honestly have no problems at all, the system runs really smooth

had some problems after the update like when quitting mh3u to menu the system crashed
but it fixed itself somehow after a few days...

now i have no problems at all, besides picky wlan which i countered with the lan adapter

No problems here. Everything's fine.

Always thought it was funny how people would use abreviations, to save time, but then they write in in full right next to it so people can understand what they mean. Killing the purpose of using abreviations in the first place.
