Software king of the world Microsoft, announced today that DX12 Ultimate was not an overhaul of the API, but a culmination of the latest technologies bundled into one. This notably includes DirectX Raytracing (DXR), variable rate shading (VRS), mesh shaders, and sampler feedback.
One of the reasons Microsoft is doing this is to unify experiences across the PC and its upcoming Xbox Series X, which will launch November 26, 2020.
These features represent many years of innovation from Microsoft and our partners in the hardware industry. DX12 Ultimate brings them all together in one common bundle, providing developers with a single key to unlock next generation graphics on PC and Xbox Series X," Microsoft said.
The main benefit for gamers is knowing, immediately, if the graphics card they are about to buy supports all the latest features.
Vole is pitching this as a way of ensuring "future-proof" feature support. There's no such thing as future proofing, of course, but DX12 Ultimate should remain relevant for at least the next couple of years.
