Vulkan is a modern graphics and compute API (Application Programming Interface) developed by the Khronos Group. It provides developers with low-level access to the GPU, allowing for more efficient rendering and better performance in applications, especially in video games. Vulkan is designed to work across multiple platforms, including Windows, Linux, and Android. One of the key features of Vulkan is its ability to handle multiple threads, enabling developers to optimize their applications for multi-core processors. This results in improved performance and reduced CPU overhead. Vulkan also supports advanced graphics techniques, making it a popular choice for developers looking to create high-quality visual experiences.
