OpenGL Extensions Viewer for Windows

OpenGL Extensions Viewer is a free diagnostic utility designed to report detailed information about your system’s OpenGL implementation. It scans your graphics card and outputs real-time data like supported extensions, version compliance, and renderer information. It includes an integrated feature, shader rendering previews, and links to specifications. 

OpenGL Extensions Viewer helps you assess whether your GPU supports the features required by specific applications. It reports on other graphics APIs like Vulkan and DirectX, offering a complete overview of your hardware. With its categorized extension list and various rendering tests, it's an essential utility for technical professionals and developers.

Technical insight and visualization tools

OpenGL Extensions Viewer (GLview) organizes your graphics data into a structured, interactive layout. Once launched, the tool detects the installed GPU and displays its OpenGL version, vendor string, and renderer ID. A categorized list of supported extensions allows quick navigation and sorting, making it easier to verify capabilities against application requirements. Each extension entry links directly to its specification, offering technical definitions for deeper inspection.

It offers real-time rendering tests to validate shader behavior. These include shader-based visualizations for tessellation, geometry shaders, and texture mapping. The rendering section provides a basic preview that helps assess how certain features perform under the current GPU driver. This is useful for identifying discrepancies in driver behavior or graphical artifacts. You can also see how your hardware handles different rendering contexts and profile versions.

The software includes performance evaluation options to test GPU performance under OpenGL calls. Results can be exported or compared to reference values across driver versions. It also displays current context profiles, including core and compatibility contexts, to help identify the exact capabilities of the installed graphics stack. This detailed insight makes the tool useful for testing environments and development pipelines. However, it does not include editing tools.

Summary diagnostics, no extras

OpenGL Extensions Viewer delivers detailed and categorized reports on GPU-supported OpenGL extensions and real-time rendering diagnostics. It does not include editing tools, optimization wizards, or asset management features. GLview focuses on reporting accurate, organized OpenGL data and offering previews of how supported features behave visually without added utilities or overlays. For tasks like performance tweaks or cross-platform simulation, other utilities will be necessary.
