NVIDIA sends word this morning that the company has posted their first DirectX 12 Ultimate-compliant driver. Published as version 451.48 – the first driver out of NVIDIA’s new Release 450 driver branch – the new driver is the first release from the company to explicitly support the latest iteration of DirectX 12, enabling support for features such as DXR 1.1 ray tracing and tier 2 variable rate shading. As well, this driver also enables support for hardware accelerated GPU scheduling.
As a quick refresher, DirectX 12 Ultimate is Microsoft’s latest iteration of the DirectX 12 graphics API, with Microsoft using it to synchronize the state of the API between current-generation PCs and the forthcoming Xbox Series X console, as well as to set a well-defined feature baseline for future game development. Based around the capabilities of current generation GPUs (namely: NVIDIA Turing) and the Xbox Series X’s AMD RDNA2-derrived GPU, DirectX 12 Ultimate introduces several new GPU features under a new feature tier (12_2). This includes an updated version of DirectX’s ray tracing API, DXR 1.1, as well as tier 2 variable rate shading, mesh shaders, and sampler feedback. The software groundwork for this has been laid in the latest version of Windows 10, version 2004, and now is being enabled in GPU drivers for the first time.
