Lag/stuttering while mouse looking has gotten unbearable

[fastboy21]

I get the stuttering also. To test it, I often go 3rd person view and swing the camera around me in a large 360 circle nonstop. When its bad I cannot get all the way around before a hickup hits and the camera freezes for a split second as I rotate. Its been worse lately, but somedays it isn't bad at all. It doesn't happen with EQlive.

I've found that rebooting my computer clears it up sometimes, but its hard to tell. Rarely it gets bad enough that I will not even attempt to solo as the hickups at the wrong critical time could kill me.
