And to a sibling comment: RX 480 is not 6 years old but actually coming up on 8 years here. Yes, these GPUs are quite old now.

People don't want to hear it but at some point graphics technology is going to have to move forward from Pascal and Polaris. You can't stay behind on legacy technology forever.

AMD knows this very well themselves: https://www.youtube.com/watch?v=fqLea0QUW1k&t=176

As Roy says: Don't be cynical, developers are not going to just stop working. But they're not going to be bound to supporting legacy pathways and obsolete APIs/feature-standards forever either. This is literally the "when developers commit from the ground-up" that AMD was referring to.

Remember, DX12U is just DX 12.2, it would have been a full api release in the past, and that eventually does come along with the old stuff eventually falling out of support. It was a pretty shortsighted move to downplay all these features for all these years, and eventually sooner or later some big titles are going to utilize them to an extent that makes a legacy fallback impossible or un-performant.

Only difference is that nvidia was the first one on the draw with this DX feature set.

GN made the case for the importance of early testing and early adoption of these featuresets, back in 2016. Then they lost their mind over Turing... https://www.youtube.com/watch?v=3qiQH29KAXg
