Why not implement these extensions right away if they are a better solution for game developers and emulators and AMD users, fans and consumers want it so much?
You mean it's the AMD company that dictates what is good or bad for its users? Does the brand's consumer opinion no longer matter? Please AMD listen to those who appreciate you with LOVE! You can see the strong feeling of Github users and right here in the AMD forums wanting these improvements so value this audience more!
NVIDIA and Intel use these extensions which are already standard for their drivers.
