This setup is with:
I originally did the DSDT override with testsigning mode on since I didn't want to risk bricking this laptop that I use for a lot of my work. Overwatch was fine, but when launching For Honor I ran into an error with EasyAntiCheat not being able to run with driver signing mode off. So I switched back testsigning mode and we back to the forums to do more reading.
I ended up doing what the poster above did and just disabled various things in device manager until it worked.
Above: the things that I disabled that worked for me have the little down arrow next to them.
It will be a bit laggy and may blue screen and reboot once or twice, but once you are able to log in and go to display settings to disable the internal display (likely monitor 1), everything works great!
I just went ahead and changed power options so I can use clam shell mode, and am happy with the results. I can now attach the razer core, boot into win10, and close the laptop.
For Honor @2560x1080 - graphics maxed!
Hope this helps someone else!
Here’s instructions how to activate the iGPU:
Can you be more specific about "disabling various things?" I disabled my AMD card and the screen went blank, restart didn't help, had to reinstall everything.
Just wanted to attach an updated device manager screenshot for you. My 1070 is on the x4 Controller... not sure if that affects the performance or speed, or if it's different from what you're seeing.
