9/10/2023 0 Comments Directx 12 release dateIt also introduces what is DirectX 12, DirectX 12 Ultimate, DirectX 12 (Ultimate) requirements, how to install the latest version of DirectX, and how to update the drivers for your DirectX 12 (Ultimate). And that's a fantastic move.This post provides a detailed guide for DirectX 12 (Ultimate) download for Windows 10 or Windows 11. The big deal here is that DirectX 12 Ultimate works the same way across PCs and the Xbox Series X, and that means next-gen titles will have the same great visuals on both ecosystems. Most of the features in DirectX 12 Ultimate are already available right now, and by bringing it under a unified suite, Microsoft is making it easier for game developers to start utilizing the latest tech. So if you bought a video card in the RTX 20 series, you'll be able to take advantage of all the new features in DirectX 12 Ultimate. Microsoft says that GPUs that are already available in the market that leverage ray tracing and variable rate shading can be branded as a DirectX 12 Ultimate GPU. With DirectX 12 Ultimate now official, we're going to see announcements from NVIDIA - and possibly AMD - about video cards that leverage all the new features on offer. DirectX 12 Ultimate is coming to video cards first The feature works in conjunction with DirectX 12's Direct3D API's tiled resource feature to render larger and more detailed textures while using less video memory. It does so by giving developers the option to load textures only when needed. Sampler Feedback reduces load times, increases visual quality, and reduces jitter. Typically there will be a phase of the mesh shader where each thread is working on a separate vertex, then another phase where each thread works on a separate primitive – but this model is completely flexible allowing data to be shared across threads, new vertices or primitives created as needed. Rather than a single function that shades one vertex or one primitive, mesh shaders operate across an entire compute thread group, with access to group shared memory and advanced compute features such as cross-lane wave intrinsics that provide even more fine grained control over actual hardware execution.All these threads work together to shade a small indexed triangle list, called a 'meshlet'. Essentially, mesh shaders turn the geometry pipeline to behave more like compute shaders, giving devs fine-tuned control: In a nutshell, mesh shaders give developers the ability to build more immersive worlds by bringing the full power of the GPU compute to the geometry pipeline. Microsoft baked variable rate shading into DirectX 12 last year, and it's unchanged in DirectX 12 Ultimate. This is a win-win situation because it takes less toll on the GPU, leading to a noticeable increase in frame rates. For instance, if there's a complex scene with several objects, the GPU is able to render the in-focus objects at higher fidelity, and objects in the background at a lower level of detail. The technique lets a GPU utilize its power where it matters most. Variable rate shading is a nifty feature that lets game developers adjust a game's shading rate in real-time. That's set to change over the coming months now that the technology is natively integrated into PCs as well as Microsoft's upcoming console.įinally, Microsoft says that games that already utilize ray tracing will be the first to pick up DirectX 12 Ultimate features. Microsoft rolled out the first version of DirectX Raytracing back in 2018, but barring a few titles, ray tracing hasn't really taken off with devs. NVIDIA was the first to roll out hardware-level ray tracing on its GeForce RTX 20 series video cards, and AMD is set to offer dedicated ray tracing cores in its upcoming Radeon lineup. Microsoft notes that it eliminates the overhead of shader-based ray tracing for simple tasks like calculating shadows. Then there's inline raytracing, which is more efficient than dynamic shader-based ray tracing in a few scenarios. Devs will now be able to invoke shaders directly from the GPU without a round-trip to the CPU, and Microsoft notes that this will come in handy for shader-based culling, sorting, classification, and refinement.ĭXR 1.1 makes it easier for game engines to load ray tracing shaders on-demand - when a player moves around a world and new objects are rendered. DirectX Raytracing 1.1 is an incremental update over version 1.0, but it introduces a few new capabilities.
