I need compile OpenCL kernels in SPIR-V to use with Vulkan, I tried with Google CLSPV https://github.com/google/clspv, but the problem occur with vectorization, functions like vload8 doesn't work. ...

I know that the present mode of the swap chain can be used to sync the frame rate to the refresh rate of the screen (with VK_PRESENT_MODE_FIFO_KHR for example). But is there a way of limiting the ...

Currently, it seems all the Vulkan tutorials and samples use NativeActivity on Android platform. I would like to know whether we can use Vulkan with Java Activity on Android?

I was following the vulkan tutorial at https://vulkan-tutorial.com/ and at the depth buffering chapter, the author Alexander Overvoorde mentions that "We only need a single depth image, because onl...

I want to play around with mobile Vulkan without having to buy a device. If it is not supported, please provide evidence (e.g. source code, official Google statements). Are there any plans to supp...

I am trying to use glslang to compile glsl shader code to SPIR-V binaries. The glslang project can be found here: https://github.com/KhronosGroup/glslang It works well via the glslangValidator.ex...

I understand that VK_DEFINE_NON_DISPATCHABLE_HANDLE is either a struct object##_T *object or uint64_t object depending on the architecture. What I don't understand is why this is used and what ben...

I am trying to use Vulkan API on my mac OS (with my Intel HD Graphics 5000 1536 Mo). But when I create an Instance With a VkCreateInstance(...) the result of VkCreateInstance(...) is VK_ERROR_INCO...

As far as I can tell it is possible for a queue family to support presenting to the screen but not support graphics. Say I have a queue family that supports both graphics and presenting, and anothe...

Problem description When I run vulkaninfo in docker, it complains: Cannot create Vulkan instance. This problem is often caused by a faulty installation of the Vulkan driver or attempting to use a G...

For writing GPU computation kernels (aka "compute shaders" in GL/Vulkan), it is useful to query various shader parameters such as register usage and shared memory usage that determine how...

Hi i'm having an error on compile. Apparently i'm missing an extension : validation layer: Validation Error: [ VUID-VkDeviceCreateInfo-pProperties-04451 ] Object 0: handle = 0x1055040c0, type = VK...

Until this point I have installed MinGW, CMake, and the Vulkan SDK. I also downloaded the GLFW precompiled binaries, GLM and PkgConfig according to this answer. Then I created a CMake project in CL...

I'm using Vulkan 1.2.170 with MoltenVK (and GLFW) on Big Sur (mid 2014 15" Retina). I created the instance with VK_LAYER_KHRONOS_validation and when I call vkCreateDevice I get the warning VUI...

Some of the mesh that I'll be using doesn't always have a DiffuseMap or a SpecularMap. When I try to load something without a diffuse and specular map the program crashes because there's nothing in...

Summary I wish to be able to measure time elapsed in milliseconds, on the GPU, of running the entire graphics pipeline. The goal: To be able to save benchmarks before/after optimizing the code (nex...

I'm currently adapting my personal engine to Vulkan and I want to reimplement transparent windows, which I already had with OpenGL. I thought that all I need to do is to select the correct color fo...
