I tested OpenGL Vs Vulkan (Zink OpenGL) gaming performance!

Latest Zink OpenGL driver (OpenGL based on Vulkan API) is tested for old OpenGL games where it did not perform so well compared to standard OpenGL driver.

OpenGL (Open Graphics Library) is an open-source, cross-platform graphics API (Application Programming Interface) that allows developers to create high-performance 2D and 3D graphics applications. It provides a set of functions and commands for rendering graphics primitives such as points, lines, and polygons, as well as for applying textures, setting up lighting and shading effects, and performing transformations. OpenGL is designed to be platform-independent, allowing developers to write graphics code that can run on a variety of operating systems including Windows, macOS, Linux, and mobile platforms like Android and iOS. This makes it a popular choice for developing cross-platform graphics applications. OpenGL operates as a state machine, where rendering states such as color, depth, and texture parameters are stored and can be modified using OpenGL commands. This allows developers to set up rendering configurations and apply various graphics effects as needed. Modern versions of OpenGL support shader programming using the OpenGL Shading Language (GLSL). Shaders are small programs that run directly on the GPU and control various stages of the graphics pipeline, including vertex processing, geometry processing, and pixel processing. GLSL allows developers to create highly customizable and programmable graphics effects.

Vulkan is a low-overhead, cross-platform graphics and compute API (Application Programming Interface) developed by the Khronos Group, the same consortium responsible for OpenGL and other standards in the graphics industry. It was designed to provide high-efficiency access to modern GPUs (Graphics Processing Units) across a variety of platforms including desktops, consoles, mobile devices, and embedded systems. Vulkan is designed to minimize CPU overhead and maximize multi-threading capabilities, allowing developers to take full advantage of modern GPU architectures. This makes it particularly suitable for applications with high performance requirements. Vulkan is designed to be cross-platform, meaning it can run on a variety of operating systems including Windows, Linux, Android, and more. This allows developers to write graphics code that can be easily ported across different platforms with minimal changes. Vulkan is designed to deliver high-performance graphics and compute capabilities by minimizing driver overhead and providing developers with fine-grained control over GPU resources. This makes it particularly well-suited for applications that require high frame rates or real-time rendering, such as games and virtual reality experiences.
