-On desktop, 3D viewer requires graphic card or software implementation supporting OpenGL 1.1 or above. OpenGL 2.1+ is highly recommended.
-Ray tracing requires OpenGL 4.0+ or OpenGL 3.1+ with GL_ARB_texture_buffer_object_rgb32 extension. Textures within ray tracing will be available only when GL_ARB_bindless_texture extension is provided by driver.
+On desktop, 3D viewer for optimal performance requires graphics processing unit (GPU) supporting OpenGL 3.3 or above.
+Ray tracing requires OpenGL 4.0+ or OpenGL 3.3+ with GL_ARB_texture_buffer_object_rgb32 extension.
+Textures within ray tracing will be available only when GL_ARB_bindless_texture extension is provided by driver.
On mobile platforms, OpenGL ES 2.0+ is required for 3D viewer. The ray tracing is not yet available on mobile platforms.
Some old hardware might be unable to execute complex GLSL programs (e.g. with high number of light sources, clipping planes).
The following table lists graphic cards tested to work with OCCT.
