Raiding in a 25man group. Getting as low as 15 fps on malkorok pulls.
Specs
R9 290x Sapphire Tri-x
I7 4770k at 3,5ghz (Because I'm lazy and still haven't bought an aftermarket cooler)
EVO 840 ssd with WoW on it.
Kingston DDR3 HyperX Predator 16GB 2133mhz
Gigabyte GA-Z87X-UD5 TH
Is this because WoW is poorly optimized or is it something that's weird about my computer?
Same build and I get shit FPS on that to, thikn about 20, some of it is down to UI, play without any addons and its alot less wank but whatever effort.
It's input lag, nothing you can really do about it, you'll notice it on garrosh HC too if you use the stack method. We narrowed it down to healing spam. Hopefully one of the things that will be fixed with the stats squish.
Others bet me to the punch, but it is input lag coming from healing output. It was first noticed on H ToT (H Meg in particular) and Blizz put in some band-aid solutions but the main fix won't come until the squish.
