Manual OpenGL initialization on QWidget

[Robert K.]

I'm initializing OpenGL on QWidget using standard WinAPI functions: SetPixelFormat, wglCreateContext, etc. and using it for continuous updating the window. Initialization is well, but I get VERY low performance. Is there is some things to do to make QWidget suitable for OpenGL rendering?

Is there some reason you're not using a QGLWidget?
