I am developing Vulkan games. It is still a basic rendering program with some cornel boxed data. Apart from testing hairs, calculating fps, what are some tools to apply to test the performance of such a program? Would also appreciate for some resources to read up on.
The Vulkan layers provide some basic performance help. They are very easy to use (can be turned on via the Vulkan Configurator) and provide basic performance diagnostics. This is a good tool to just turn on and run regularly, its output gives enough info to look up whatever issue it finds in the spec. It even provides a basic fps calculator. The tool can be found in the vulkan install location bin/vkconfig.exe. Once the tool is running look under message severity and make sure performance is checked.
Render Doc: There is a dedicated Vulkan layer just to help out with using RenderDoc. It is advertised as a debugger but provides excellent information about GPU state which is very helpful with many performance tasks such as helping tweak shader programs.
Vulkan itself provides performance aids like VK_KHR_performance_query. Use vkcmdwritetimestamp (google it for pages that help with its usage) to time commands in a vulkan queue.
As you can image the list goes on and on, but these are some good places to start.
