Here are screenshots of all my settings on Razer Blade Pro 17". You can see in the last one that despite "correct" settings, opening a Windowed Output on my GUI screen shows that Intel is rendering there. I believe this is why performance is getting crushed with any kind of external display hooked in.
I additionally tried setting the texture renderer to High Performance in NVidia settings, but that didn't make any impact on performance and caused the videos to stutter and look generally bad.
