Client freezes whenever I kill a mob (that gives xp?)

[Bozena]

I haven't done extensive testing yet, but every time I've killed a mob that gives XP (so far, in Kith and Velks), my client freezes. I've checked other threads and have turned down spell density and other graphic effects, as well as turned off Loading Art (since I was also freezing while zoning, sometimes). Any suggestions would be very welcome!
