[osg-users] force vsync to false (sofware not hardware) on NVidia

[Jan Ciger]

Hello,

I am prototyping some OpenGL stuff in Python using Pyglet and have
encountered the same vsync problem, both in Linux & Windows. I think
it is Nvidia's driver that is (again - Nvidia had various vsync issues
in the past) trying to be smart and is breaking vsync in OpenGL. It
has most likely nothing to do with OSG.

For me if the vsync setting in the driver is set to application
controlled, it is always on, no matter what the application specifies
(vsync=False or vsync=True in the gl.Config setup in Pyglet makes no
difference). The only way to turn vsync off is to disable it in the
driver's control panel.
