They were quite open about concentrating on DX12. And really, I think that those who were dreaming of 3080 / 3090 / 69xx performance were hopelessly optimistic. This is Intel's first try in many, many years.
It's not really though is it, they own the integrated and frankly we should expect better. How many years have they been writing drivers for? Anybody would think they are entirely new to market the way they are going. They aren't they have been writing GPU drivers for some 20 years poorly, extremely poorly. They even claim in one of those interviews that they don't write gaming drivers yet iris pro etc were partially sold on integrated gaming prowess... Mark my words this will be comical.
