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:

Vulkan GuideGet Started in Vulkan

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 VulkanCreate tutorials that explain the implementation of best-practices and include performance analysis guidesCreate a framework that can be used as reference material and also as a sandbox for advanced experimentation with Vulkan
