And by that time, AMD's next generation RDNA 2 / Navi 2x graphics cards will be available.This post provides a detailed guide for DirectX 12 (Ultimate) download for Windows 10 or Windows 11. Not that we have any games that require everything currently available, but those might start showing up next year. Future additions to the DirectX API will occur, of course, but at least every DX12 Ultimate GPU will have at a minimum the same capabilities as the Xbox Series X. That also means that, while Nvidia's RTX 20-series GPUs are currently the only DirectX 12 Ultimate capable GPUs, that won't be the case once AMD's RDNA 2 and Navi 2x GPUs arrive later this year - a Navi 2x GPU will be present in the Xbox Series X.įor PC gamers, the benefit of the DirectX 12 Ultimate branding is that you'll know that the hardware you're purchasing supports the latest complete feature set. One of the major purposes of DirectX 12 Ultimate is to provide a unified target platform for both PC and the upcoming Xbox Series X. Microsoft has a detailed explanation of sampler feedback (opens in new tab) and why it's important, but the key takeaway is that it could potentially mean a game would only need to commit (access) one tenth as much memory. Finally, sampler feedback basically allows for a more efficient use of VRAM. Mesh shaders were previously an Nvidia extension and allow for the more efficient processing of large amounts of data. VRS enables higher performance by running fewer shading calculations on surfaces that are deemed less important - areas where the extra detail (eg, a flat colored texture) won't matter visually. Along with DXR 1.1 and DX12 features, Variable Rate Shading (VRS) tier 2, Mesh Shaders and Sampler Feedback are all part of the new DX12 Ultimate API.
