I want to write multimedia application to run particularly even on intel gma 3150 videocards. I can't decide what to use: a game engine or qt. Application contains text, image data and interactive 3D environment that is displayed from time to time (not often). In a case of Qt I have to built in a part of a 3D engine into application and use a lot of QGraphicsItem components, but in a case of game engine, I have a problem of fps on intel gma 3150 videocards.

So what do you advise?
