DX12 was backed by the biggest OS maker & Vulkan by Khronos & both are industry standards as well as IHV independent. DLSS is Nvidia only, for now, we'll see whether RTX & DLSS gain traction the way some think they will - probably too easily just because it's Nvidia?All technologies are the way forward until they're not. Like Vulkan and DX12.
Oh, I remember in the days of Fury when we were told all games will become DX12. Still, 3 years on? Hasn't really happened. This is Nvidia's turn at predicting the gaming future.
Frankly, I have no idea....
