VK_NV_RayTracing on Pascal GPU


In one of the articles about new GeForce drivers, I read that Pascal GPUs with at least 8GB of VRAM should support the Vulkan Ray Tracing extensions, however when I tried to run the VKRay sample on my 8GB GTX 1070, It showed an error message that said my GPU doesn’t support the required extension.

Does Pascal really support the RTX extensions? In release notes it says that only Volta and Turing support this extension, however on gpuinfo.org, there were some Pascal GPUs that supported this extension.

I don’t know about VK_NV_ray_tracing, but since we have VK_KHR_ray_tracing now since Vulkan 1.2, I guess the latter is what is of interest.

I can confirm that VK_KHR_ray_tracing runs on Pascal generation GPUs without any problem. You might just need the Vulkan 1.2 Developer Beta Driver.

For an example application, I can recommend maierfelix/ VK_KHR_ray_tracing
