Return of Reckoning

I have 30-50 fps in rvr fights what is ok for me (atleast for now)
But when I join wb sometimes i am droped to ,,slideshow''
What I mean, today I fight in t3 elf, first attack on destro keep was good in FPS.
After we wipe on kee[ lord, and try again i get this. 1-3 fps drops.
And this is not fights like 100vs100, sometimes it happened even in ~10vs10
Is there any solution for this? ofc I am not speaking about ,,go solo''.
Maybe I just skipped solution hide somwhere on forum?

Core - amd phenom II x4 850 3,30 GHz
RAM - GB
Win 7 ultimate 64 bit

(I know this PC is not even decent for today, but this do not looks like pc config problem)

what elven said ^
But if you experience these drops on so many different occasions, maybe you can still do some troubleshooting. Monitor your temps and try disabling your addons. Maybe you find a something that helps a bit.

I experienced it always in wb fight (as I said no matter the scale of it)
Temp are ok, I always monitored it after some event I get with it.
Interesting think is, If I get this fps drop, and leave warband it is almost instantly return to normal.

My blind shot is: Somehow I get too many ,,useless'' combat logs, informaction, pack of this ect, that make this drops.
But why I get it, and why randomly (I think it is randomly) I have no idea.

Try disabling party/wb frames (either default or addon frames, such as Pure/Squared) and see if it helps at all.

it usually fixes FPS drops

if in rvr zone get into a non rvr zone fixes this for me or the other way around. If it happens on a non rvr zone getting into an rvr does the trick.
