Playing videos/streams crashes Sierra almost instantly

Recently installed the Sierra Public Beta and everything is working beautifully, but playing videos causes my hackintosh to crash.

Followed the advice from this post: http://www.insanelymac.com/forum/topic/300022-playing-videos-crashes-my-hackintosh/

I set Inject Intel and set the ig-platform-id to 0D220003 but I'm still getting crashes with active content.

I have a natively supported gpu so I don't think that'd be causing issues.

My build for reference:

Intel i5-4670K
AsRock...
