hi

I've read the stickies and done a search, but nothing I found seemed to address my problem.
so at the login screen, I get a ping of 1000-2000 - this is normal, I live in east africa with a pretty bad connection, and this sort of ping is pretty standard for me. but when I go in the game, my actual lag is about 10 seconds or so - for example, when i try to loot a rat after ive killed it, it takes like 10ish seconds before the loot window pops up, and sometimes the rat even disappears and then I get a reply saying 'there is no target selected', even though i typed /loot right after the rat died :S
my system is:
osx 10.5.5
3GB ram
128MB graphics card, ATI Radeon X1600 (i have added the two line fix for the X1600 card, to see if it would do anything, but it didnt work)
2.1 ghz intel core2duo
I've turned off sound, shadows, and put on adaptive distance..helps very slightly. what could be the cause of this extra lag?
[I made this topic in the newbie forum, and one reply said it could be a mac-specific problem, so i'm asking here too

)
thanks for any help!
