HUGE FPS/Performance Drop w/Patch 9.1.5

I logged into WoW tonight and it was almost unplayable, my FPS dropped significantly to 10-15 FPS. I play WoW a few times per week on the same MacBook Pro 16 (2019 - highest end model) that I’ve been using for over a year and have always had great performance with a steady 80 fps on graphics level 6.

Now, regardless of what graphics level I set my game at, whether it’s 2, 3, 4, 5, 6 my FPS does not improve and the game is extremely slugging, remaining at 10-15 FPS.

I noticed other reports on this forum so I wanted to add another voice because the game is unplayable in fast-paced environments such as mythic keys and PVP.

I checked Activity Monitor, my CPU idle is 79%, so it’s definitely not CPU related and I don’t use time machine. These 2 points were brought up by a Blizzard rep in another thread. Even if I disable mods, no improvements. I have tried everything at this point. Also note I am not using any external monitors, I play straight from the laptop.

Please look into this asap, as I am not going to continue subscribing for a game I cannot play. Thanks!

Yup, same, 2020 iMac Retina 5K 2020 AMD Radeon Pro 5500 XT 8 GB.

Oribos and Bastion are slide shows.

All addons disabled.

M1 iMac and I’ve got the same thing. 1/3 of my usual FPS.

Same exact problem. It didnt even give me an update when the patch went live, Hopped on and 20 fps. Now trying to fix the problem im stuck scanning and repairing…99% and then oops something broke. Have no clue what to do.

I am experiencing significant fps loss as well. 2017 iMac 27in 24gb ram. Radeon pro 570 4gb 3.4 ghz core i5. Previous patch dropped fps to a consistent 60,which is acceptable. This patch 20’s to 40’s. Mostly in the 30’s. Still running Big Sur.

It was my post where it was suggested to turn off indexing etc. it didn’t help me. I haven’t logged in today but I’m not feeling optimistic seeing all the posts on here today.

Seriously wtf bliz?

no one said turn of indexing, I said to open activity monitor to see if it or something else still running.

@Blizzard - Can we get an official response for our Mac users with an ETA on when we can expect the hotfix?

Cancelled my subscription - When it’s fixed, I will resubscribe.

I just can’t reproduce this. no performance difference from 9.1. it still has the 9.0.5 performance regressions near conductors but nothing new in 9.1.5

I tested in Coffee lake hackintosh that’s cpu bottlenecked that still gets 60fps everywhere on ultra (it’ll never push 120 fps do to shadowlands zones being to cpu bound, sadly) and a brand new M1 Max Macbook pro 16

In fact, I couldn’t even confirm the user who has a macbook pro and their reported performance issues either.

With M1 max it gets 120fps on ultra all settings at native resolution using FSR 50% and is super crisp. FSR is a game changer for retina macs. I really suspect a lot of users with performance issues are not using it and have render scale at 100% on 4-5k resolutions.

Omegal - you are the only Mac user I know not having the issue… help a brother out? What should I do?

Same issue here on a Big Sur 5k 27" Intel iMac. On 9.1, on 10 settings, I would get on average maybe 80fps. Once I installed 9.1.5, that dropped to 15-20fps. Changing settings to 4 only brought it up to 25-30fps. Something is seriously wrong with this patch.

there are others not having issues too. I know my friend mooni with her like 5 year old imac is doing fine, better than fine ever since FSR was able to take her performance up with this patch.

I’d triple check graphics settings and make sure render scale didn’t get reset to a value that’s too high for a retina screen. it should be at like 50% not 100% then turn fidelity super resolution on in advanced options to make everything crisp as max render scale but with performance benefit of 50.

I’d also run activity monitor and see if anything else is stealing processing power. it really is pretty common for a large patch to trigger large time machine backups or spotlight indexing to occur and if those tasks not yet complete

incompatible addons can make performance slow to a crawl too. Make sure addon situation is squared away.

Lastly, for SOME dumb reason every patch blizzard resets fps cap to 100. that can cause machine to run too hot, overheat and throttle. most macs have a 60hz screen which means any frame rate higher than 60 is totally useless. Set fps cap to 60 to ensure machine is not over working for no reason. or turn vsync on which will max frame rate to screen refresh automatically.

Does FSR work with all the supported GPUs in Macs that can run WoW (M1, AMD and Nvidia)? It specifically name checks AMD in the settings panel.

I’d like to add I have no issues either. I’m running a 2017 iMac 5K with an AMD Radeon Pro 580 8 gb, latest version of Monterey. Quality is set to 8 with Shadow and Liquid set to Fair.

On Retina Macs (and likely any 4k or 5k screen), you absolutely have to make sure the Resolution scale is set to 50%. FSR will do the rest (make sure it’s enabled in Advanced).

In fact, the graphics seem to have improved and the game is running at a steady 60 FPS. I turned off anti-aliasing, no more need thanks to FSR.

One notable thing I’m seeing is that far-away nameplates are rendered much crisper than before. I assume that’s because of FSR. Before, they were hard to read with a Resolution scale set to 50%.

FSR is all GPUs, it’s made by AMD for everyone. a departure from nvidia’s DLSS which is nvidia only hardware.

It even works on intel IGPU

My “Resolution Scale” was 100%, I changed it to 50% and that certainly helped. But I didn’t change that before.

I Just hit hte “Recommended” Button. But it wants 100%, so I’ll knock that back down to 50%. So I’m at “Setting 7”, with the 50% scaling. This is netting me 35fps in Ardenweld. I also did the 60FPS thing (which didn’t change my FPS, but if it makes the fan kick in less, it’s a win).

And, no, my CPU is fine – 87% idle.

100% render scale too high for just about any mac. set to 50 but make sure fidelity super resolution is enable in advanced options for resampling

Did that (thanks for the tip), it helped, but the minute I got into the rested zone, boom. Freeze freeze crash. Will tinker more tonight, but it ain’t looking good.

Is there an updated video settings guide anywhere for Mac’s? The pinned post is very outdated. Thanks

I set my graphics to a 1. still no help.
