Introduction

The Vulkan Samples is collection of resources to help you develop optimized Vulkan applications.

If you are new to Vulkan the API samples are the right place to start. Additionally you may find the following links useful:

Performance samples show the recommended best practice together with real-time profiling information. They are more advanced but also contain a detailed tutorial with more in-detail explanations.

Goals

  • Create a collection of resources that demonstrate best-practice recommendations in Vulkan
  • Create tutorials that explain the implementation of best-practices and include performance analysis guides
  • Create a framework that can be used as reference material and also as a sandbox for advanced experimentation with Vulkan

Usage

The following shows some example command line usage on how to configure and run the Vulkan Samples.

# For the entire usage use
vulkan_samples --help

# For subcommand usage use
vulkan_samples <sub_command> --help

# Run Swapchain Images sample
vulkan_samples sample swapchain_images

# Run AFBC sample in benchmark mode for 5000 frames
vulkan_samples sample afbc --benchmark --stop-after-frame 5000

# Run bonza test offscreen
vulkan_samples test bonza --headless

# Run all the performance samples for 10 seconds in each configuration
vulkan_samples batch --category performance --duration 10

# Run Swapchain Images sample on an Android device
adb shell am start-activity -n com.khronos.vulkan_samples/com.khronos.vulkan_samples.SampleLauncherActivity -es "cmd" "sample swapchain_images"
