macOS 12.3 Update Causes Problems for 5700/6800/6900 Graphics Cards

[tmaxxtigger]

Be aware that if you're running a 6800/6900XT there are serious performance issues with 12.3, my geekbench score dropped by about half.

RX6800 slow in OS12.3 Beta

My previously speedy Gigabyte RX6800XT has taken a performance hit in the Beta of 12.3 Monterey? Lou

AMD 6900XT, performancce dropped significantly not just in benchmarks but games as well.

Before update, 120fps on WoW on ultra settings. post update, 40fps on same settings, and to get even 60fps have to turn settings to low/medium....Apple utterly gutted performance of GPU in this update.

if you are using a navi 2 card, AVOID this update like plague. in fact I'd gut software update to make sure this update is never allowed.

Current macOS Version: Monteret 12.2.1
Current GPU: Gigabyte AMD Radeon RX 6800 XT

Regarding: macOS Version: Monterey 12.3

Considering the specifications listed above, I received the 12.3 update request, last night, and saw on the 12.3 forum page that some people are experiencing issues with their AMD Radeon RX 6800 & 6900 XT GPUs, after the update. All comments were a bit vague. I still have not made the update, but am concerned for the potential performance drop that a few have mentioned they've experienced, after this update. I do not use it for games on macOS, but I do use it for music, video, effects & animation production. Premiere and After Effects are very demanding of it. The update comes with updates for GarageBand and Logic Pro, also, so outside of the potential performance loss, the update is a factor to me.

Does anyone have any more information on this?

Thank you.

I updated to MacOS 12.3 and I can confirm that with my 6900 XTXH, the Geekbench 5 scores are impacted. My Metal benchmark is about 50% slower than in 12.2

Edit: Verified with Unigene Heaven. That benchmark is also reporting halved performance.

If these numbers are important to you over keeping your Mac up to date, I would hold off on the update.

6800xt is completely useless in 12.3

After upgrading to 12.3, other than showing up in the "System Report", it seems that the 6800XT does not (do any) work.

Running neatbench gives a 94% drop in GPU performance, it's actually now slower than the CPU.

Please, rename this topic to All NAVI issues for 5000-series and 6000-series!

This is a very big problem! I never trust to geekbench and prefer the real task. So, my 5700 XT under 12.3 became useless.

My Motion (5.6 v.) project viewport preview drop from 17FPS to 7 FPS!
Blender EEVEE (3.1 v.) project increase render time from 18 sec. to 28 sec.!

Basically performance drop on all fronts – Metal, OpenCL, OpenGL !

Interesting. I would speculate that hardware acceleration is somehow disabled in 12.3 for those cards.

What does the system profiler and VideoProc settings display?

Have you tried any of the overrides to force using the dGPU? (https://github.com/acidanthera/WhateverGreen/blob/master/Manual/FAQ.Chart.md)

E.g.


defaults write com.apple.coremedia hardwareVideoDecoder


Also note that there has been a recent change in WhateverGreen related to GVA being enabled by default (in case you are relying on that, see - https://github.com/acidanthera/WhateverGreen/releases/tag/1.5.8)

VideoProc is Ok.

I don't understand how video encoder/decoder could be link with Metal/OpenGL graphic performance in Blender EEVEE or Apple Motion with just particles project (without any video files).

There hardware acceleration in 12.3 is enabled but 1/2 performance of Mac OS 12.1/12.2/12.2.1.

Version of AMD driver under 12.3 is '4.1 ATI-4.8.13' by the way. (4.7.100 was previous as i remember).

I tried to use WhateverGreen v.1.5.7 but it doesn't effect. I don't understand how to used "enable-gva-support"; is it just boot argument? Should i use it as "-enable-gva-support"?

Here is another thread with that problem:

While I try to render a blender or motion project I could see GPU loading with Activity Monitor. And yes, GPU is under load. But overall it feels that I have half of full performance. My own test with real software confirms that (i don't use geekbench).
