I can't believe that I'm saying this - but I don't think that it's correct blaming QA or the devs. I would have to assume that management pushed the dev and QA teams to release a full list of features no matter what, and that's what they did. I assume that the schedule was extremely harsh and QA and devs were raising all of the alarms, but management just told the to ship whatever even if it's alpha or beta quality at best.
There's no way the devs/QA don't know the state of what they were releasing - it has to be the management that's telling them to ship whatever no matter what.
This, almost certainly, and it probably belongs in Raja's lap.
If they had just not turned on those features, and told marketing to keep quiet about them, they could quietly keep working on them after the card release until they are ready. Then users would get a pleasant surprise in the future, something good for building brand loyalty.
Focus on the basics first, get that working 100%, then do the bells and whistles for the vocal 5% who care.
Honestly from that video, the smart thing to do right now would be to have it automatically disable those features entirely for anything running that is using less than DX 12. Problem solved.
What's unforgivable though are the issues with inability to install patched drivers, inability to uninstall the drivers, and essentially breaking the box requiring a complete OS re-install (3X according to GN) to get it fixed.
This is *exactly* the thing with video drivers that had me switch from AMD GPUs in the 2000s to Nvidia about a decade ago. I am in a mood to give AMD another chance, but it's been 10+ years, those kind of screw-ups have long term costs.
