OpenGL performance in QT in 2D graphics, who knows what?

Question

Programming

Hello. There is a project written in Qt, QGraphicsView/Scene is used to draw a 2D scene and work with it. The fact is that with a large number of items, everything starts to decently and noticeably slow down when scrolling and working. Actually, the question is, will there be a performance increase if all this is drawn not using QGraphicsScene, but rewritten to work with OpenGL?

Answer 1

Something similar was discussed in this thread . But, purely theoretically, nothing can be more productive than working with pure OpenGL.
