Intermittent client lockups.

[Pyronasty]

Does anyone else have this issue or know how to fix it?

Seemingly randomly I get like a 1/2 second to 1 second lock up where the game freezes. This has happened as long as I can remember but I just ignored it because it was infrequent (every few minutes) and very brief. However I started AE kiting on a Bard and this is making it impossible as I just die every time one of these freezes occurs.

I have turned every graphical setting possible to the lowest, set CPU affinity to a single processor, changed Windows to highest performance settings, tried timing the lockups to see if it occurred at a regular time interval, none of this has done anything.

I could have 100 mobs on my screen and lock up or I can just be running through an empty area and lock up. There doesn't seem to be any correlation to anything that I can see.
