/** @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. |
