Are you reading the post I responded to? I'm not saying Doom is flawless (I just lost a good chuck of progress.)
Silver is flat out accusing id of taking a bribe from NV. Come on, at some point people are going to have to just accept it - AMD drops the ball.
I would give Silver the benefit of the doubt if this was a Gameworks title. It isn't.
I'm not accusing id of taking a bribe, I am open to the possibilities that several things could have happened, one of which is the Pascal marketing deal. Are you saying it's an impossibility?
Sure, AMD can and does drop the ball. But here?
How does AMD decide to regress back to an OpenGL version released from 2012 when it was running the newer version just fine in Beta 2 weeks prior? AMD does not control Bethesda/ID Software's final build. -_-
We're talking an out-date OpenGL that's missing a lot of newer extensions that enhance performance here.
I am not the first to notice this, many folks have asked ID Software this question on social media, they aren't saying anything as to why it happened.
Even some reviewers noticed it, because they played the beta as well as some of us here.

And oh, when the game finally gets updated to fix it, by putting back OpenGL 4.5 for AMD, make sure you guys are here to say stuff like "oh, it must have been an honest mistake, surely!!"

Actually, on that note there is one issue with Doom and it could go a long way in explaining why the game runs poorly on AMD hardware at launch. Some keen enthusiasts noticed that the game uses the latest OpenGL 4.5 version when running a GeForce graphics card, but it reverts back to the much older 4.3 version with a Radeon graphics card.
Apparently this wasn’t the case in the open Beta, so the plot thickens. A few days ago id Software's lead renderer programmer Tiago Sousa was quizzed regarding the issue and he said "looks like ultra settings ( beta was a mix of medium ), particularly shadows ( and couple other things ) - AMD working on it." We assume by this he meant there's an issue with Radeons when using the Ultra quality settings, though we found it reverting when using high, medium and low settings as well.
Can you even think for a moment if this happened to NV? Imagine a DX game, which had a beta 2 weeks before launch, running DX11 great for NV/AMD... then it releases, it reverts to DX10 for NV and performance is crippled. Even a non-biased person would have to raise a real concern as to why it happened, no? Now let's say that studio went on stage with AMD hyping up AMD GPUs... what's a logical person to think of such a thing? Come on, be honest.
