Greetings Hugh, I was playing around with Vulcan awhile ago and these may be of interest: Vulcan Tutorial: https://vulkan-tutorial.com/ Khorno's Maintained Github of Vulcan Examples: https://github.com/KhronosGroup/Vulkan-Samples I've looked through it briefly and there are lots of various types of examples. From playing around it seems you need to have a working knowledge of certain parts of C++17 or later. Not sure this helps with your interest in GPU programming, Nick
