I am at a loss trying to figure out what is causing this but what I can tell is that if I disable all mod the FPS issues go away. This is NOT a latency issue (35-40ms while this happens) and instantly goes away when I drop combat.
As of 3.3.0a when I am in 25m raid (ICC, TOGC, etc) and enter combat I drop from 120fps (Non-combat) to 5fps.
This is really odd because it does not happen in battlegrounds and it may be happening in 10m raids but it does not hinder my game play or my FPS nearly as much.
Is there a mod or way to tell which mod may be causing this? Anyone else experience this since the patch?
I use a lot of mods but the common raid mods I use are...
Well the thing is and why I suspect it is a mod -- FPS is 100% fine in AV, 5mans, even 10mans but 25m raids (Any 25m TOGC/TOGC Heroic/ICC/etc) -- 5fps when I enter Combat and then it shoots up to 120fps out of combat.
I suppose you will have to disable your mods and enable them one by one (or half by half) to figure out if any particular addon is causing issues, since you are sure that if they are ALL disabled, you have no issues.
Try disabling Skada, I've noticed some odd fps drops as well lately in 25mans (can't test this at the moment though as my guild is on a raiding break for the holidays) and it's the only addon I use from your list.
I do use Tinyplates but have since disabled it -- same thing happens. I turned skada off and installed recount was still horrible but i'll try turning both off next time (and no i don't usually run both I perfer skada but was trying to test mods that interacted with the combat log mid icc bosses (cant miss rep!!).
