Which addon lags of these?

Hello,
running a dual-core amd(3400hz) with 4gb of ram and a 512mb graphics cards and yet still if i leave all my addons on in raids, my fps drops from 60 (party) to 4-10, sometimes even less. In 10man it's not that big of a problem, 20 fps is enough. I haven't been able to find out whats the cause of it by disable/enable options so was hoping that if someone might have an idea what might be wrong?
Minimal video settings + projected textures on. Audio turned off

addon list during raids
pitbull4.0
deadlybossmods
bartender
combuctor
fubar : guild, durability, friends
kgpanels
skada
satrina buff frame
pallypower
outfitter

or is it something i've done wrong with the config files? or something completely different?

High chance
pitbull4.0
bartender
skada
kgpanels

Don't know/maybe
fubar : guild, durability, friends
satrina buff frame

Your damage meter has a high chance especially if it gets worse as fights progress or during AoE. Might I also say that you do have an awful lot of panel mods, any chance you could consolidate?

Only panel mod he has is kg, maji.

Update your Pitbull4. There were a few versions that used to cause pretty heavy lag.

if it's pitbull then i have to play a lot of guesswork to find the stable one again. Curse updates it atleast twice a day >.>

Also, would you say dominos is better for non-lag than bartender? Think i read that somewhere ages ago...
Really love most of the features in Bartender which are missing in dominos last i checked

Just keep your Pitbull up to date. I know they were messing around with the text display lately, but if you keep the most recent version before you have to raid you should be fine.

it indeed was pitbull. Tried updating it and the lag droped by a bit. Then turned it off and the lag went away completely.
Any other addons that are nearly as configureable but casue no lag?
Was thinking 3.0 but that is not being developed anymore?

Xperl is good, but you still might get some lag. It doesn't really cause me any problems. ( i do turn off animated portraits)

XPerl is not good. It's fugly as sin and has about zero customisation options.

xperl will also cause you to dc quite a lot if your getting lag spikes or too much happening on the screen at once. Might not be the case so much if you have a great connection and good computer but i have a shitty connection and i have to turn it off whenever i raid. I just use grid to see my raid and classtimer for the debuffs on boss that i have to keep up.
