Prior to this, the requirements for Mac and PC were lower at macOS 11.6 or later and Windows 7 or later, respectively. The PC must have at least 4 GB of RAM, 8 GB recommended, an x86-64 CPU and a GPU supporting one of the supported graphics APIs: OpenGL 4.3 or greater, or Vulkan, the latter being recommended.
In Direct3D 11, the concept of feature levels has been further expanded to run on most downlevel hardware including Direct3D 9 cards with WDDM drivers.. There are seven feature levels provided by D3D_FEATURE_LEVEL structure; levels 9_1, 9_2 and 9_3 (collectively known as Direct3D 10 Level 9) re-encapsulate various features of popular Direct3D 9 cards conforming to Shader Model 2.0, while ...
The High-Level Shader Language [1] or High-Level Shading Language [2] (HLSL) is a proprietary shading language developed by Microsoft for the Direct3D 9 API to augment the shader assembly language, and went on to become the required shading language for the unified shader model of Direct3D 10 and higher.
Direct3D 12 version 1703 – With the Windows 10 Creators Update (version 1703), released on April 11, 2017, the Direct3D 12 runtime has been updated to support Shader Model 6.0 and DXIL. and Shader Model 6.0 requires Windows 10 Anniversary Update (version 1607), WDDM 2.1. New graphical features are Depth Bounds Testing and Programmable MSAA.
SPIR-V 1.0 is a new version of SPIR announced in March 2015, [11] and released on November 16, 2015. [12] The SPIR family now includes a true cross-API standard that is fully defined by Khronos with native support for shader and kernel features. A separate program by the Khronos Group allows for interconversion with LLVM IR. [13]
Other functions like abs, sin, pow, etc, are provided but they can also all operate on vector quantities, i.e. pow(vec3(1.5, 2.0, 2.5), abs(vec3(0.1, -0.2, 0.3))). GLSL supports function overloading (for both built-in functions and operators, and user-defined functions), so there might be multiple function definitions with the same name, having ...
Each Compute Unit contains 64 shader cores. [7] CUs are organized into groups of two named Work Group Processors with 32 KB of shared L0 cache per WGP. Each CU contains two sets of an SIMD32 vector unit, an SISD scalar unit, textures units, and a stack of various caches. [ 8 ]
DirectX 10 (Shader Model 4) and Cg 2.0 introduced geometry shaders. [6] DirectX 11 (Shader Model 5) introduced compute shaders and tessellation shaders (hull and domain). The latter is present in Cg 3.1. DirectX 12 (Shader Model 6.3) introduced ray tracing shaders (ray generation, intersection, bit / closest hit / miss).
