Nopes, but i'll give that a shot now 

I'm in the midst of that right now as well. Let's hope for the best.
Edit: So people have reported that a flash drive install fixes this problem. I tried that earlier with no luck but it was on an existing file that already had the issue. So I cleared the flash drive and started a new game with it installed on the drive and it did nothing...
So I guess we can debunk this flash drive installation rumour. Though people have been reporting it works, maybe they just got lucky. That or they don't know what a low res texture looks like and were unable to properly identify any sort of issue either way.
