Unsupported OpenGL features

Some functionality, which is either soon-to-be deprecated or isn't proven to add any performance gains, is not supported in Magnum. See also Deprecated OpenGL API list.

Unsupported features

  • API that is not part of core profile or is marked as deprecated (but still supported in core profile) in the latest version of OpenGL specification is not supported. The only exception are features that are needed for some OpenGL ES 2.0 implementations (such as luminance texture formats).
  • State queries (various glIs*(), glGet*() functions) are not supported. Magnum API is designed to prevent the need for majority of them, many of them are tracked internally to avoid redundant state changes and in many cases it is easier to set the state to some value rather than query it and then decide on the result. For detailed state introspection please use external debugger (such as ApiTrace), which is more convenient to use than manual queries. Queries of implementation-defined values (various limits etc.) and queries of generated values (buffer data, texture data) are supported.
  • Line and polygon smoothing (GL_LINE_SMOOTH, GL_POLYGON_SMOOTH) and related functions are not supported, as the driver might do it in software with serious performance drops. Multisampling is far superior solution.
  • Fixed precision data types (GL_FIXED in OpenGL ES) are not supported, as they occupy the same memory as floats and they aren't faster than floats on current hardware anymore. They are also not available in WebGL or desktop GL.
  • Shader compiler is assumed to be present (GL_SHADER_COMPILER returning true), as all desktop GL implementations and also ES3 are required to support it.
  • Querying shader attribute locations (as opposed to setting them) is not supported, as newer GL versions encourage setting them explicitly in shader code.
  • Direct vertex data specification (as opposed to using buffers) is not supported, as it encourages bad practices.

Unsupported ARB / Khronos extensions

Unsupported vendor extensions

  • INTEL_map_texture negatively affects texture access performance. Combination of buffer mapping and pixel buffers might be of the same or better performance, without affecting texture access speed.
  • NV_draw_texture can be done with framebuffer blitting and doesn't make any full-screen postprocessing easier, as shaders are excluded.
