Slow Graphics Performance MacOS High Sierra

That didn't help. Turning off scaling helped.

Despite several users suggesting in this thread that the newer downloadable drivers directly from NVIDIA provide better graphics performance, you do not appear to have Installed them.

Thanks! Yep, unplugging my external monitor seemed to resolve my issue.

MacBook Pro (Retina, 15-inch, Mid 2014)

2.5 GHz Intel Core i7

16 GB 1600 MHz DDR3

Intel Iris Pro 1536 MB

NVIDIA GeForce GT 750M

Hi guys, after months of pain I just downgraded to Sierra, my macbook pro is finally working again 🙂

I did the exact same thing: switched back to Sierra and everything is smooth again. Unfortunately I didn't run any tests but Im pretty sure you're on to something here. BTW I have a Late 2013 Macbook Pro which is using the same GeForce 750M graphic card.

Changing resolution fixed it for me, we'll see how long it lasts; not ready to install nvidia drivers yet, I would have bought a PC if I wanted that. This is all related to the fact that High Sierra’s window server runs through Metal now. It was supposed to make it faster and more efficient but obviously there are teething issues.

For me the Nvidia driver helps but only partially. For my regular work it has made this bearable and my fans aren't on constantly. However if I play a 3D game I still get terrible FPS, no improvement there.

My conclusion is that the Nvidia driver seems to make things a little better, depending on what you're doing.

FYI my configuration is a late 2013 Retina MBP with NVIDIA GeForce GT 750M 2 GB.

Apple's QC leaves much to be desired

NVIDIA is likely at least partly to blame for this problem. They have been unwilling to provide the deep detailed operation of their graphics chips, which has made it impossible for Apple to write new Drivers.

NVIDIA has been "late to the party" as evidenced by your now being able to get newer drivers direct from NVIDIA web site.

¿Where were these "updated" drivers when the software was originally released? The approximate schedule was not a secret, but NVIDIA was not there with updated Drivers or the information to allow Apple to write Drivers.

Downgrade is completely possible, but it requires a BLANK disk. You MUST have at least one complete Trusted Backup to proceed.

I'm not sure if Time Machine backup would allow restore from 10.13 to 10.12, that would make life easy.

You can only go backward to a Blank drive.

But you could erase the drive (provided you had a good backup) and Install MacOS (older version) on it. When you do the last Restart, it comes up in Setup Assistant, and will ask you if you want to create a new User, or restore from Time Machine, or import from anther source.

The issue is nothing to do with installed apps. It’s problem with nVidia graphics drivers. I do exactly same as you wrote, but result is still same. Only downgrade to macOS Sierra is the solution.

May I ask what is wrong with CleanMyMac app? I’m using it about year or more and works great. Mainly for apps uninstallation.

I have a few MacBook Pro's of various sizes and ages, so I have nVidia and Radeon both suffer under High Sierra. It's not an nVidia only issue.

When you do a full Shutdown / Reboot does your machine go fast? I haven't seen the issue after a full Shutdown.

I only see it about 60% of the time after a sleep - on both nVidia and Radeon ...
