glmark2 is a graphics benchmark designed to measure the performance of OpenGL 2.0 and OpenGL ES 2.0 implementations. It runs a range of rendering workloads covering areas such as texturing, shading, model rendering, and graphical effects, which makes it useful for comparing graphics drivers, GPUs, and Linux graphics stacks.
This is free and open source software.
Key Features
- Supports multiple Linux graphics backends including X11, Wayland, DRM, and GBM offscreen rendering.
- Offers configurable benchmark scenes and per-scene options from the command line.
- Can run in fullscreen or off-screen modes for different testing scenarios.
- Includes validation support to help check benchmark correctness.
- Can export benchmark results to XML or CSV.
- Reports additional metrics such as CPU time and shader compilation time.
