I am currently having very bad lag on my PS3 only, and it's very puzzling to me how the game can run so well on both PC's in the house, but on the PS3 the game lags terribly and is unplayable.

Previously the game has run very well on the PS3 but for the past 1-2 weeks the game is not playable due to severe lag / freeze ups and disconnects (error 90,000) on PS3, with no signs of improvement. In fact the problem was the opposite around the time the game released - I could play without lag on PS3 while the PC was un-playably laggy.

I can't understand how the connection on PS3 vs PC can be so different on the same network? Surely the PS3 and PC connect to the exact same game server?

I'm with orange broadband and did suspect throttling issues when the PC was lagging over a month ago, but now I don't know what to think as surely throttling would affect the game on all systems in the house?

Can anyone help me diagnose where the problem lies and whether I can fix it on my end (or if changing ISP would help). I don't know what information / tests to do so please advise and I'll post extra info.

Any help will be really appreciated, and thanks in advance.
