No problems here... yet. Granted, I've only got maybe 40 hours of playtime combined the last 2 1/2 weeks because of the log in clamping.

Something I've been wondering... are you guys running on the high end of the quality settings and such? I've been running the Standard Desktop profile with a few things like shadows and such toned down or disabled.

Just wondering if maybe it's not tied to something funky like fetching components for specific effects/texture maps or something that is tripping things up. Otherwise, maybe an issue with something not getting downloaded properly with all the congestion?
