Since 8.1 launch I’ve been having bad latency spikes and in general it takes half a second for a spell to actually cast, this hasn’t been an issue in the past but makes the game really clunky to play.
Home and world ms both around 40.
Anyone have an idea how I can improve this?
Running on a late 2015 iMac.
Edit: further testing, it improves or gets worse based on zone and whether war mode is on or off, could this be a sharding issue from blizzards end?
I have been having a similar issue. I’m on a 2017 21 inch iMac. I had no issues with the game before 8.1. There was an update to Mac the day after the Patch went live. I have tried changing settings and removing AddOns. It might be my internet at peek times, but the latency even happens outside of those times.
I’ve had a TON of lag issues since 8.1. Before the patch, it was 30-50ms regularly. Now, it’s regularly 150-400ms. Completely unacceptable.
Same problem. It doesn’t seem like I actually have network latency, just a lot of input lag. Even if I put settings super low while using an RX580 eGPU setup it gets laggy and worse than before 8.1. FPS is ok in small areas with no people but as soon as I enter an “epic” BG I cannot play.
Same issues here. Complicated for me since I have a US account / play on US servers but live in the U.K. now. *. Game was working fine before 8.1 (not brilliant but fine). I have a late 2013 27 inch iMac (last generation before retina)
(* I’m from US originally and don’t want to have to start from level 1 again by moving to EU servers).
@Kelt, It looks like you and I have the same model iMac. My experience after 8.1 was horrible, and since my main is a healer, you can imagine how that went.
After doing some research, I found a post on Reddit (which I think was copied from here) advising of an app called EasyRes
The problem with our Macs vs Wow is that the graphics card renders the game to the full size of our desktop resolution then downsamples to whatever resolution you have the game set up as --lots of wasted clock cycles, and given we’re running the 780M, we’re already behind the 8ball.
The app EasyRes easilly/quickly allows you decrease your desktop resolution prior to launching the game. It also has a “preview pane” so you can see the aspect ration of your choice prior to committing.
I choose the res setting one step below native, and that doubled my framerate in game to a consistent 60fps. You won’t be able to run the game at Ultra, but “good” is better than “low” 
If you want nerdy details, follow this link:

This app made the game playable, and not so bad looking for me again… at least until the 2019 iMac refresh is available.
Cheers.
Thanks, I will give that a try! Appreciate the feedback.
How does this work for MBP?
Yes, it should; essentially it forces Mac OS from wasting gpu resources in rendering the game at your native desktop resolution then downsampling to whatever your game resolution --it’s a “1x” gpu rendering process.
If you want to squeeze some more FPS out of your game, I suggest you use EasyRes to set desktop at least 1 step lower (in resolution) than your MBP’s desktop resolution, then launch the game. You will see that the actual resolution will be greyed out (you cannot adjust the Px) on the System/graphics panel which is excellent, just make sure to keep the scale of your action bars at 1.0.
Using this strat, I can still keep all of my effects settings (on the right side) to at least “High” and view distance at 7 and environment detail and ground clutter at 8 which a consistent 58-60 FPS —which is excellent for my tired 27" Late 2013 iMac.
Let me know how it goes.
Cheers!
I’m a bit late to the party, but I’ve found that using an app called SwitchResX makes things (more) playable for me. My desktop has an ultra-hi-res monitor so I don’t normally run at max res outside of games – and WoW no longer lets you specify what res to run at. If I’m not a† the highest, the game scales – and drops my performance in half, at least. So SwitchResX lets me define a resolution PER APPLICATION – WoW runs, it switches to highest res, WoW quits, it drops back.
However, I’ve also been having unrelated input and response lag since 8.1… makes playing a Fire Mage difficult because Heating Up often doesn’t show until I’ve almost finished casting my next Fireball. For healing, instant spells aren’t so instant…
Makes life rough.

FWIW, most of us are probably still playing on High Sierra because NVidia has yet to release Mojave drivers for their Pascal cards. I do run Mojave on my MBP with the Vega 20 GPU and I have the same kinds of lag as I do on my High Sierra Mac Pro (2009, but 5.1 ROM).
I will say that I have not seen slow loading but I have SSDs for all but backup drives.
8.1 fixed a number of my issues (especially things like single-FPS graphics in raids and some WQs) but the input lag got worse.
EDIT: also wanted to add that if you’re not playing WoW at your monitor’s native resolution, then the game scales its graphics and you get ALL sorts of slowdowns.

I had a post “hidden” up here and am curious. Since a GM told me to post what I did so the Mac Tech people could see it.
There was no spam, there was no commercialization. There was no other violation that I am aware of.
It dealt with what is a known server end problem called sharding, as explained by the GM who asked me to post here the post I had posted elsewhere.
And as of yesterday it was still happening.
