Our verdict on glmark2

glmark2 is an open-source command-line benchmark for graphics-performance testing on systems with compatible OpenGL or OpenGL ES drivers. It supports OpenGL 2.0 and OpenGL ES 2.0, with platforms listed for Windows, Linux, and Android. It suits developers, system evaluators, and technically oriented users who need configurable graphics workloads rather than a broad, general-purpose benchmarking suite.

Its main strength is control over the workload. Users can select individual benchmark scenes, adjust scene options, load custom benchmark descriptions from files, and control rendering and window parameters. The published category specifications list 33 benchmark presets, while the feature set also includes off-screen rendering and visual-configuration controls. Multiple backends—including X11, Wayland, DRM, and Android—help align testing with different graphics environments. Results include FPS, CPU time, and shader-compilation time, and can be exported to CSV or XML files for later analysis.

The trade-off is a narrower comparison and workflow model. glmark2 focuses on OpenGL and OpenGL ES rendering rather than a wider collection of graphics APIs or workloads, and its command-line design places more emphasis on configuration and result handling than on a guided interface. It also does not provide online comparison, so cross-system evaluation depends on how users collect and interpret exported results. Choose glmark2 when open-source licensing, configurable scenes, multiple rendering backends, validation, and file-based reporting matter most. Consider a broader benchmark suite when online comparison or wider graphics coverage is the priority.
