when I run the ray_tracing_ao demo,
it crash at: void HelloVulkan::createCompPipelines()
VkResult res = vkCreateComputePipelines(m_device, {}, 1, &cpCreateInfo, nullptr, &m_compPipeline);

in this function ,it crashes.

Hi yao tang!

I've just verified that the latest version should work (my system has Vulkan SDK 1.2.189 and NV driver 471.55) - could you give me more information about the system you're running on and the crash? Specifically,

• What GPU are you using?
• What GPU driver version are you using?
• Would it be possible to get a minidump when it runs into the crash?

Thanks!

@wiltchamberian, it works also for me, but I'm also using 1.2.189.0 and a very recent video driver. The graphic card is GeForce RTX 3060 Ti, which is supporting VK_KHR_ray_query. If you have all of the above and still fails, check if the shader is compiled and loaded one line above.

  cpCreateInfo.stage = nvvk::createShaderStageInfo(m_device, nvh::loadFile("spv/ao.comp.spv", true, defaultSearchPaths, true),
                                                   VK_SHADER_STAGE_COMPUTE_BIT);
