Good evening! I'm planning to port my graphic engine to Qt. Currently it is based on FreeGLUT, but Qt is of course a much more powerful toolkit.
I make use of (GLX/WGL)_swap_control_tear extension through GLEW, it allows to use a negative swap interval. This is very useful to limit CPU usage without the risk of dropping the frame rate.
Does Qt support it? QSurfaceFormat::setSwapInterval doc says nothing about it.
