What measurement/monitoring tools could I use to get the FPS values for a simple Vulkan app?

Thanks in advance

  • $\begingroup$ @PaulHK I am looking for a tool to measure the FPS of my very simple app. I am new at this; nowhere near to instrumenting my application. $\endgroup$

    $\begingroup$ @Vectorizer: If it's your program, you should not be using FPS as a unit of performance measurement. Use the actual frame time instead; it's far more useful. $\endgroup$

Try AMD's OCAT tool. It can overlay an FPS counter on a Vulkan or D3D12 app, similar to how FRAPS works for D3D11/OpenGL. (It should work on all Vulkan-supporting GPUs, btw, not just AMD ones.)

You might want to try the VK_LAYER_LUNARG_monitor layer from the LunarG Vulkan SDK.

Download the SDK from the LunarXchange site.

After SDK installation, you can activate the layer by setting this environment variable:

VK_INSTANCE_LAYERS=VK_LAYER_LUNARG_monitor

The monitor layer displays the FPS value in the application window's title bar.

  • $\begingroup$ Cool stuff!. @SimonF you just add the extension string to the array of your validation layers and it just works )) $\endgroup$

  • $\begingroup$ Unfortunately, it didn't work for vulkansdk-1.2.131.2 on ubuntu 19.10 for glfw-based app, although such layer loaded properly as inspected via VK_LOADER_DEBUG=all. But anyway, it works with vkcube. $\endgroup$

  • $\begingroup$ Nowdays, with the Vulkan Configurator (included in the SDK) you can enable this layer more easily. Tested on Win10 x64. $\endgroup$
