What graphics cards from NVIDIA, AMD, or Intel support DirectX 12 Ultimate? This means that a simple driver is not enough to implement these technologies, nor is it possible to access them using shader programs, which implies the purchase of new hardware. For example Ray Tracing requires intersection calculation units in the shader units of the GPU, DirectStorage requires a new memory controller, Variable Rate Shading new raster units and ROPS, what’s more, even Mesh Shaders require changes in the processor. Why is this happening? Well, for the fact that these require the addition of additional hardware within the GPU to be able to implement. So if they are an essential requirement in a game then it will no longer be possible to execute it, even if it has plenty of power to do so. designed for said API, since there is the exception of not having support for the technologies that we have mentioned in the previous section. This does not mean that all GPUs on the market with DX12 support can run the games. The fact that Microsoft has not baptized the new version of its API as DirectX 13 gives us the clue that the new API is an extension of DirectX 12. Why don’t standard DirectX 12 cards support the Ultimate version? With resolutions with millions of pixels per frame it results in savings and increased performance by eliminating redundant operations.Īll of these technologies require profound changes to the internal GPU hardware, which limits the number of GPUs that have full support for all of these technologies. Variable Rate Shading: designed so that the GPU does not perform the same operation several times with totally symmetrical pixels.Sampler Feedback: a technology that allows the graphics processor to choose what exact data it requires from the SSD instead of taking entire blocks of data where a good part only ends up taking up space in the VRAM.DirectStorage: technology that serves for the integration and access to NVMe SSDs from the graphics card, which opens up new scenarios in which the size of the VRAM is virtually unlimited.Mesh Shaders: games have more and more complex geometry thanks to the greater number of details, which means that the stages of the 3D pipeline in charge of managing it have become outdated and a renovation has been necessary.For practical purposes this means more precise shadows and real reflections on objects. Ray Tracing: Ray tracing is one of the greatest graphic advancements, as it solves visual problems with indirect lighting, as well as the nature of light on objects.However, it must be clarified that this is a quick summary of them, so you will find more complete information in the different articles that we have made here in HardZone. In DirectX 12 Ultimate, new technologies have been added, so we have thought to list them one by one so that you can see the advantages of adopting the new API for video games.
