I do feel for you Shankly. Like you say, that is a lot of questions that you can not answer alone. You are indeed only one man and that is a task that requires dedication. In other news, I liked the fact that Vega was awesome from day 1 and great to see it. I remember too many times that AMD have been so slow with performance and needed drivers that came out a few months later.
No need to feel for me mate, I have a wife for that
It's one area that used to disappoint me about Amd, after say since the release of crimson software Amd have been excellent getting day one drivers out, even beating nvidia at times!
If nvidia need more time on upcoming Dx12 games to get better performance, you after also ask the question what happens with older GPU series does nvidia keep optimisation for them also. "nvidia are known to drop support for older cards" least that's the story anyway.
I.e older GPUs fade away when compared to other amd GPUs from that time frame.
