FULL SWIFT SHADER 2.1: A Comparison with Other Software Renderers and Hardware Accelerators



The project started as a way for Google to bring full hardware acceleration for WebGL to Windows without relying on OpenGL graphics drivers. Google initially released the program under the BSD license.[13]




FULL SWIFT SHADER 2.1



Ola pessoal eu vi que tem muintas pessoas que tem um pc nos requisitos minimos para o the elder scrolls IV mais quando está terminando a 1 parte e ta entrando no esgoto para ir para mundo aberto o jogo fecha do nada eu tenho a solução para isso é só colocar o swift shader 2.1 mais como eu sei que é tenso jogar com aquele banner ridiculo na tela eu modifiquei o arquivo e tirei o banner pra vocês segue o link do swaift shader 2.1 sem banner


Standard Portable Intermediate Representation (SPIR) is an intermediate language for parallel compute and graphics by Khronos Group. It is used in multiple execution environments, including the Vulkan graphics API and the OpenCL compute API, to represent a shader or kernel. It is also used as an interchange language for cross compilation. SPIR-V was introduced in 2015 by the Khronos Group, and has since replaced the original SPIR, which was introduced in 2012.


The purposes of SPIR-V are to natively represent the primitives needed by compute and graphics; to separate high-level language from the interface to compute and graphics drivers; to be the distribution form, or distribute fully compiled binaries; to be a fully self-contained specification; and to support multiple APIs. It is also used as an intermediate target for cross-compilation tools.


SPIR-V 1.0 is a new version of SPIR announced in March 2015,[9] and released on November 16, 2015.[10] The SPIR family now includes a true cross-API standard that is fully defined by Khronos with native support for shader and kernel features.


SPIR-V is a high-level intermediate language, exchanged in binary form. Functions are represented by a control-flow graph of basic blocks, using static single assignment (SSA) form. Data structures retain high-level hierarchical representation. It is not lossy like previous byte-code or virtual machine-like intermediate representations used for graphical shaders. This allows closer to optimum performance on the target devices.[16]


Graphical shaders use structured control flow in SPIR-V to state how control flow nests. This helps in defining divergence and reconvergence of control flow on parallel execution environments.[19] Specialization reduces the number of variants of a shader that need to be distributed.[20]


SPIR-V can express calls to functions in a different compilation unit. The standard version of SPIR-V uses this feature for OpenCL compute kernels, but not for shader stages, which the graphical APIs want fully linked into a single SPIR-V module.[22] There are extensions available to allow tools to temporarily use partially linked shaders and also kernels.[23]


SPIR-V has been used to help deal with multiple versions of source-level languages. For example, the multiple versions of OpenGL Shading Language (GLSL) require distribution of multiple versions of shaders, due to implementations that are pegged to a specific older version of GLSL, such as for WebGL 1.0 and Apple's OpenGL implementation. One of the notable use cases of SPIR-V is its ability to be used as an interchange format between GLSL versions, using tools maintained by the Khronos Group for compiling GLSL to SPIR-V glslangValidator,[25] optimizing SPIR-V spirv-opt,[21] and cross-compiling to SPIR-V to different GLSL targets spirv-cross.[26]


As a format, however, SPIR-V has some limitations for cross-compilation, including the requirement that every SPIR-V module have at least one entry-point symbol. This prevents the format from being easily used for separate compilation, where complex shaders could be assembled by a series of partial compile steps followed by a linking step. This runs counter to the stated goals of some SPIR-V tools such as spirv-link,[21] which aims to provide full linking functionality for SPIR-V binary code.


DXTweaker aka DirectX Tweaker spoofs values but apps/games do some additional checks and do not detect shaders 3.0. By the way, it only exists as time bombed beta and you need to set date in VM to somewhere in 2005 to get it working if you want to try its tweaks.


The example below uses a lazy stored property to avoid unnecessary initialization of a complex class. This example defines two classes called DataImporter and DataManager, neither of which is shown in full:


Simply create several textures (all with the correct and same size !), call glFramebufferTexture with a different color attachement for each, call glDrawBuffers with updated parameters ( something like (2,GL_COLOR_ATTACHMENT0,GL_COLOR_ATTACHMENT1})), and add another output variable in your fragment shader :


NVIDIA consistently provides industry leadership to evolve new Vulkan functionality such as ray tracing and DLSS AI rendering and is often the first to make it available to developers. The NVIDIA Nsight suite of development tools, has integrated support for Vulkan, including debugging and optimizing of applications using full ray tracing functionality. NVIDIA ships Vulkan on PCs, embedded platforms, automotive, and the data center. And gamers enjoy ongoing support of the latest Vulkan API changes with older GPUs going back to Maxwell.


NVIDIA provides a growing collection of Vulkan and OpenGL samples and tutorials with full source code available on GitHub. Developers can download the samples that interest them, from educational introductions to basic Vulkan workflows and extensions, through examples of how to render scenes with high geometric complexity and ray tracing,and on to professional application use-cases. The repository also contains utility code that can speed up Vulkan development.


We'll provide useful examples and resources to make a basic integration of Vulkan ray tracing and traversal in an existing Vulkan raster sample. With the help of an existing online tutorial, we'll review the main steps of a simple ray tracer. From the location of SDKs and drivers to the debugging tools such as Nsight to set up the appropriate environment, we'll lay the foundation for the step-by-step addition and activation of ray tracing. We'll also cover specific topics related to ray tracing, such as any hit shader, intersection shader, reflections, animations, shader record, multiple hot shaders, callable shaders, and ray query.


NVIDIA GPUs are incredibly powerful and with the arrival of DXR and Vulkan Ray Tracing, it's now possible to do Ray Tracing at interactive framerates. Even so, it can be a challenge to ensure that you are fully utilizing the GPU efficiently. In this session, you'll learn about the available tools and features available to developers that can help you take advantage of this incredible innovation to improve the graphics in your game.

suite of functions.These provide a full set of type conversions between supportedscalar,vector, andother data types except for the followingtypes: bool, half, size_t, ptrdiff_t, intptr_t, uintptr_t, andvoid.


The __attribute__((opencl_unroll_hint)) and__attribute__((opencl_unroll_hint(n))) attribute qualifiers can be usedto specify that a loop (for, while and do loops) can be unrolled.This attribute qualifier can be used to specify full unrolling or partialunrolling by a specified amount.This is a compiler hint and the compiler may ignore this directive.


Block variables hold references to Blocks.You declare them using syntax similar to that you use to declare a pointerto a function, except that you use ^ instead of *.The Block type fully interoperates with the rest of the C type system.The following are valid Block variable declarations:


l (ell) Specifies that a following d, i, o, u, x, or Xconversion specifier applies to a long or ulong argument.The l modifier is supported by the full profile.For the embedded profile, the l modifier is supported only if 64-bitintegers are supported by the device.


l(ell) Specifies that a following d, i, o, u, x, or Xconversion specifier applies to a longn or ulongn argument; thata following a, A, e, E, f, F, g, or G conversion specifierapplies to a doublen argument.The l modifier is supported by the full profile.For the embedded profile, the l modifier is supported only if 64-bitintegers or double-precision floating-point are supported by the device. 2ff7e9595c
