You have to re-do it every time you re-start your mac which is a pain, but at least it saves all those writes to your disk

Thank you duncamn!

Here's a quick and dirty shell script to automate the finding of the PID

#!/bin/sh
pid=`ps -ax | awk '/SkyLight.framework/ && !/awk/ {print $1}'`
echo "Skylight.framework with OpenGL logorrhea PID found. Suppressing log for PID $pid"
sudo log config --process=$pid --mode "level:off"

Put that in a file 'quite-dlink' in your $PATH, chmod 0755 it and execute it in Terminal at startup.
