Graal has issues. Mondo issues.

[MoonShadow]

My graal logs on perfectly normal, but after a little while, the b drops to 0 or jumps to the insane number of 8000 and fluctuates for a little while. This happens mainly when I am around people, but happens a lot when I'm not around them nonetheless. I've reinstalled/uninstalled graal several times, and I am forced to use the G3D client (the problem is with the G2k2 client). I don't know what to do, it's network lag and problem has nothing to do with vid. card issues, as I am running on a fairly advanced GeForce4 440, on an AMD Athlon 64 3000 processor. I've already tried messing with UDP, Direct3D, and stuff like that, nothing works.
Any and all help will be very welcome and appreciated.
