Monsterous lag on just a single toon?

Hey guys... I've been having this problem for a few months now. I partially solved it by shelving the toon for the past few months, but now I wanna start playing it again, lol. So I need to see if someone can help me with this issue.

Basically, whenever I play my Fire/Kin I have extreme lag issues the moment I start a fight. The second I hit Fire Cages my FPS goes down to next to nothing. I'm lucky if I catch 2 or 3 frames of the entire fight before I see myself dead on the ground. I can't activate any powers, nor I can do pop and inspirations or do anything at all, rendering that character completely unplayable. I tried using unloadgfx and sync and reloadgfx and a bunch of other stuff. No help at all.
Weirdest thing is, that problem is completely exclusive to my Fire/Kin. I have absolutely no issues playing my other toons. Including my my other Fire controller (Fire/Rad). Hell, I've been on an All controller STF before where we had 3 Ill controllers (5 pets per), 2 Fire controllers (3 pets per, plus hot feet and choking cloud) and 2 Earth controllers (massive graphics) on the team and I"ve had absolutely no lag issues at all. So I know the problem isn't my graphics card (a built in intel graphics card, BTW).

Also, I think it's worthy of mention that this problem started out of no where a few months back. I used to be able to play my Fire/Kin normally with no lag issues at all.

Anyone has any ideas why is this happening? It's been annoying me so much I"m considering just deleting the toon all together...but I really enjoy playing my Fire/Kin. Not just because he's my farmer toon, but playing him is actually fun on missions/TFs as well. So, any kind of suggestions or help would be really helpful.

Thanks a lot

You're best bet is to ask in the technical issues forum. The experts there will hopefully be able to help you. That sounds like a really strange issue.

Alrighty..thanks.
