/** @page unsupported 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.

||
|

@section unsupported-features Unsupported features
|
||
|
|
|
||
|
|
- Luminance texture formats (OpenGL ES) are not supported, as they are
|
||
|
|
deprecated in OpenGL ES 3.0 and not present in core desktop OpenGL.
|
||
|
|
- Fixed precision data types (OpenGL ES) are not supported, as they occupy the
|
||
|
|
same memory as floats and they aren't faster than floats on current hardware
|
||
|
|
anymore.
|
||
|
|
|
||
|
|
@section unsupported-extensions Unsupported extensions
|
||
|
|
|
||
|
|
- @extension{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.
|
||
|
|
- @extension{NV,draw_texture} can be done with framebuffer blitting and
|
||
|
|
doesn't make any full-screen postprocessing easier, as shaders are excluded.
