just discovered the strangest behavior with my hack.
Its running for quite some time and its pretty reliable, I'm happy.
But now I wanted to get rid of my GPU-Throttling problems once and for all.
So I did some testing with windows and the onboard-card and used an energy-meter to clearly see when the gpu is throttling.
Don't ask me how I found out in the end, but:
When Starting the machine and booting into MacOS it runs at about 130W at idle - way to much.
( Under windows its idling at 90W - thats better. )
BUT: When starting MacOS with my Monitor plugged out and only plugging it back in when the boot reached the login-screen: solid 90W!
I did some Benchmarking: performance is exactly the same, but Idling/Throttling actually works flawless then!
Repeated this quite some times, always the same outcome:
Booting with Monitor plugged in: 130W Idle.
Booting with Monitor plugged out: 90W Idle.
So, guys. Do you have any idea why GPU Idle/throttling only works when I'm booting with my monitor plugged out (and then pluggin it back in at login)?
And the next quesiton: How to fix this?
