I didn't know that DX12 has been "forgotten" by developers. Personally, I think DX12 is doing fine, it's just ramping up slower that DX11 did. Things will change once more people have DX12 capable hardware.
At first glance, this looked like the performance boost all budget gamers would adore, encouraging the widespread purchasing of DX12-capable video cards. 18 months on from the launch of Windows 10 the reality is that there are only 16 titles with DX12 support and a couple more in the pipeline. Which begs the obvious questions: why don’t developers love DX12, and is this becoming a significant issue?
