macOS High Sierra 10.13 slow graphics after battery sleep

2017 MacBook Pro 3.1Ghz

Having upgraded to macOS High Sierra 10.13, the graphics have slowed down significantly after sleep.

Steps to reproduce:

1. Close lid (default power settings)

2. Unplug from mains power

3. Wait 1 hour

4. Open lid and login

5. Try a graphics intensive app or game and notice a slow down?

Is this a known issue?

- Have a tried a clean install of 10.13.

- Have tried reverting to 10.12 (problem does not exist on 10.12.6)

The only option is to reboot.

MacBook Pro TouchBar and Touch ID, macOS High Sierra (10.13)

After another week of testing, I have found that when I change my macbooks sleep mode to "sleep" instead of the default "safe sleep", this problem does not occur anymore...

Use this command to check your current sleep mode...

pmset -g | grep hibernatemode

Default is 3. I set mine to 0.

sudo pmset -a hibernatemode 0 - to set the desired sleep mode.

0 - Old style sleep mode, with RAM powered on while sleeping, safe sleep disabled, and super-fast wake.

1 - Hibernation mode, with RAM contents written to disk, system totally shut down while “sleeping,” and slower wake up, due to reading the contents of RAM off the hard drive.

3 - The default mode on machines introduced since about fall 2005. RAM is powered on while sleeping, but RAM contents are also written to disk before sleeping. In the event of total power loss, the system enters hibernation mode automatically.

5 - This is the same as mode 1, but it’s for those using secure virtual memory (in System Preferences -> Security).

7 - This is the same as mode 3, but it’s for those using secure virtual memory.
