It is weird that this has been latched onto so easily when there's nothing else to back this up. Until now it was widely accepted that supply issues caused some delays and now suddenly it isn't supply issues.
I suppose if there were performance issues then we should see Doom running even better than it was shown almost a year ago.
That was also a rumour that started on WCCFtech if i remember correctly.
And that's the thing: In the absence of real numbers and statistics, the usual suspects latch on to rumours and make them facts. The argument that "no news is bad news" does not hold up here and the imagination of a few sites shouldn't be taken as gospel.
Let me see official reviews and let's leave speculation at the door.
Don't believe this, but it'll be easy to prove. If it's a driver/performance issue then we should see a hard launch of RX Vega, sooner rather than later, and there will be hundreds of thousands available on release day. It's not like there's only so many drivers to go round.
Why are supply/yield issues more believable than driver issues?
Considering this is a company who in the past has been slayed by everyone for releasing products before the drivers where ready. Just look at Ryzen launch reviews. Also Raja, did point to having difficulty coding the drivers.
