having the same problem here, i don't want5 to re-install the updates because some idiot is stealing my wi fi and downloading them again wil take FOREVER
I only get slow load times if I boot into GT5 with my wheel plugged in, if I boot first then plug it in, it works fine. Other than that, everything else seems fine.
Edit, clearing your cache doesn't always help. If you don't do it regularly, don't do it, if you have been doing it, its fine. I haven't cleared my cache since the last update (2.07?), it works much better than it did when I use to clear it everyday.
