Well since you were so quick to add gameworks between E3 and Launch... I will keep my comment and thoughts about that to myself and it's direct results of it has caused.
But when will those of us using AMD gpu's get GPUOpen on Fallout 4 if ever? I know AMD is probably not paying you to put it in, but it allows you to use an open source method so Both Nvidia and AMD users could benefit from it giving you full control of extra eye candy, its performance and tweaks.
