Now, I'll start by saying I raid 10 man in a laptop, not very fancy, and I rarely have fps issues. Sure, they are never too high (15-25 depending on the boss), but it's enough to play decently. I play with all graphics set to minimum (except boss' spells one, it's set to high).

My problem arises when I raid 25 man, specially LFR. I do ultraxion a lot of times to try different rotations and whatnot, and sometimes I feel like my 20 minutes of queue and 5 minutes of trash go to waste as soon as the fight starts. I have absolutely no lag whatsoever, and when the boss is pulled, someone pops Time warp and my fps are gone. Sometimes the screen just freezes for periods of 3-4 seconds, sometimes I get down to about 0.5 fps, and the suddenly, after a minute or two everything goes back to normal.

Just today I was doing Madness LFR and when I Reached the last platform it was chaos. Alternations between screen being totally frozen, to sub 1 FPS.

I also doubt addons are causing this. I play with nothing but recount, bartender, omnicc and clcret. Apart from recount, all of these are extremely light . Regarding recount, I sometimes close it down to do these fights, but these retard things still happen.

Any idea of what I can do?
