What differences between two installers?



  • What differences between the "Qt 5.1.0 for Windows 64-bit (VS 2012, 525 MB)" and "_Qt 5.1.0 for Windows 64-bit (VS 2012, OpenGL, 522 MB) _" installers?

    Is the first version draws GUI via CPU, and the second version draws GUI via GPU?

    Thank you.



  • No, read the note bellow the "download section":http://qt-project.org/downloads:

    bq. The Windows offline installers are by default ANGLE based. If you want to know more about the differences between ANGLE and OpenGL packages on Windows, please visit "Qt 5 on Windows ANGLE and OpenGL":http://qt-project.org/wiki/Qt-5-on-Windows-ANGLE-and-OpenGL.

    It's all about using OpenGL implementation directly or using ANGLE that implements a subset of OpenGL API (OpenGL ES 2.0 right now) on the top of DirectX calls for achieving better speed and compatibility on windows.
