It works! It runs the Gtx 1080 with Razer Core perfectly. My only issue now is that Windows is stuck in Test mode - anyone know if this is fixable?
Some helping tips that made it work for me:
(On a 2016 Macbook Pro 15 inch with 2.7 cpu and 460 AMD GPU)
Using this guide:
1. Download Windows Binary Tools and then WDK and install them (from the '"Tools Required"section), it felt like you needed those apart from the pre-package. Windows Binary Tools has many options, I chose the Express version.
Once you download and install them make sure you check the WDK folder in your downloads folder and run the installer from there.
2. Use the iasl -g command in step 2, you don't need the acpidump command
This is what you need to do to get the process started for the guide:
Download the tool pack http://www.mediafire.com/file/y686pbfr8zdvea1/2570P-dsdt-override.rar
On the terminal screen (press the command button in keyboard and search 'command prompt'- right click and run as admin) , you have to type "cd [address of the folder the files are on], then press enter to move to that directory and then the commands will start working
So for example cd C:\Users\bagpipehero\Desktop\2570P-dsdt-override
(cd stands for change directory I believe)
Then just type iasl -g and click enter, and then go through the next steps using the command prompt when needed and editing the text document when needed.
3. On the parts of the guide when you have to type in dsdt.dsl, check if your file name is different. Mine was DSDT_MacbBookP.dsl so it worked when I typed that in instead.
4. When it finally works ('Large Memory' appears in device manager as shown in the final step) you will get an error 34, just install latest drivers for your gpu. Windows takes 2.5 minutes to boot up so need to be patient.
5. Once it finally works, go to device manager 'sound, video and game controllers' and disable Cirrus Logic, press ok to restart computer. When it restarts just re-enable it and your sound will work.
6. Bonus fix: If you are having trouble moving and shooting in games, go to mouse settings in windows -> touchpad -> set it to no delay. This freaked me out for a second but works well now!
I wish I could teleport and do it for you guys as it is so quick after this stuff finally makes sense!
