It's a technique that lets game developers dial shading rate down in those areas of a scene where it matters less, therefore saving performance, while the shading rate goes up in the most important areas. We already discussed Variable Rate Shading at length on Wccftech.

Both the dynamic-shading and inline forms of raytracing use the same opaque acceleration structures.

It is available in any shader stage, including compute shaders, pixel shaders, etc. Inline raytracing is an alternative form of raytracing that gives developers the option to drive more of the raytracing process, as opposed to handling work scheduling entirely to the system (dynamic-shading).Streaming engines can more efficiently load new raytracing shaders as needed when the player moves around the world and new objects become visible.Basically, scenarios that prepare raytracing work on the GPU and then immediately spawn it. This ability is useful for adaptive raytracing scenarios like shader-based culling / sorting / classification / refinement. Raytracing without an intervening round-trip back to the CPU. This enables shaders on the GPU to invoke GPU Work Creation now allows Raytracing.No longer do the cycles operate independently! Instead, they now combine synergistically: when Xbox Series X releases, there will already be many millions of DX12 Ultimate PC graphics cards in the world with the same feature set, catalyzing a rapid adoption of new features, and when Xbox Series X brings a wave of new console gamers, PC will likewise benefit from this vast surge of new DX12 Ultimate capable hardware!ĭirectX 12 Ultimate is comprised of four main features: DirectX Raytracing, which gets updated to version 1.1 Variable Rate Shading Mesh Shader and Sampler Feedback. Even when hardware was similar, the software interfaces were quite dissimilar, discouraging aligned adoption by developers.īy unifying the graphics platform across PC and Xbox Series X, DX12 Ultimate serves as a force multiplier for the entire gaming ecosystem. Prior to DirectX 12 Ultimate, there was limited overlap between these two cycles. Announced today during “DirectX Innovation Day” ( a stream on Mixer that replaced the canceled GDC 2020 talk), it promises to usher in next-generation graphics across both Windows PC and Microsoft's Xbox Series X console in a much faster way than previous API advancements, as explained by Microsoft below. DirectX 12 Ultimate is the latest iteration in Microsoft's API for game programming.
