[Did SL get laggier, or is it just me?]

Alright, so I stopped playing for a few months, before Is stopped everything was fantastic, I used firestorm or Exodus without a problem! But I recently returned to find that both those viewers, even phoenix, lag horrible, THE ONLY VIEWER THAT WASN'T LAGGING WAS THE OFFICIAL ONE! What a surprise right? I also noticed a lot of new...SL features.

[All items equipped.]

Good to know I am not the only one. While this accordance has happened to me before with other viewers, it has NEVER been this bad.

[All items equipped.]

Some viewer (could've been firestorm or phoenix) equiped all my inventory items, how would I go about fixing this if everytime I attempt to unequip them the viewer freezes and disconects. Any solutions or simillar tales?

[Gravity reversal.]

ok, so i was following this guy trolling him and his "partner" and all of a sudden he turns gravity upside down for my friend adn I but he and his partner are fine. How is this accomplished / reversed?
