I took a 1 1/2 break - 2 months and before this I never had any such problems where i've had such bad lag. None of my software has changed since then.
Now I cannot even PVP because my ping will raise up to about 3k and fps will drop. I was in ab and when there are no other people near me the game is playable but the fps is still crappy but once other people or mobs show up I lag so bad that I cannot even tell whats going on. The only thing I can do is some pve/solo farming and it still wil lag some.
I did the defragment thing on my c drive last night but that has changed nothing...

I was also told I should try to redownload the gw.dat file? to remove the current one and put it somewhere else because it might corrupt... would this help?
Any help would be great!
