DX12 works well cause it was designed to make driver development easier. Last gen APIs required specific optimizations in drivers for every single game in order for it to run well. And as far as I heard the problem isn't in drivers, problem is in hardware scheduler that have some kind of limitations that become more apparent with scale. It might be impossible to fix this without retape.
