Hello Mario!
> how to get it to use my Nvidia GPU instead of integrated graphics
Usually I need to go through this process:
1. From the 'NVIDIA Control Panel', go to '3D Settings' > 'Manage 3D
Settings'.
2. Select the tab 'Program Settings'.
3. In the section 1., click on 'Add' and select your own .exe, then in
section 2. select the 'High-performance NVIDIA processor'.
4. Click 'Apply'. Restart your program; it should now use the NVIDIA
processor.
I had the possibility to further "tune" the parameters for my programs on a
previous laptop, but I can no longer change anything on this one (e.g.
enable/disable vsync).

Unfortunately, there is no repository for this, nor a mechanisms that lists
the keys/buttons handled and what they do. You'll need to check the code of
the different classes that handle movement to see what they do and how they
do it. In osggpucull, the entry point is probably around this code:
osg::ref_ptr<osgGA::KeySwitchMatrixManipulator> keyswitchManipulator =
new osgGA::KeySwitchMatrixManipulator;
keyswitchManipulator->addMatrixManipulator( '1', "Trackball", new
osgGA::TrackballManipulator() );
keyswitchManipulator->addMatrixManipulator( '2', "Flight", new
osgGA::FlightManipulator() );
keyswitchManipulator->addMatrixManipulator( '3', "Drive", new
osgGA::DriveManipulator() );
keyswitchManipulator->addMatrixManipulator( '4', "Terrain", new
osgGA::TerrainManipulator() );
I hope this helps you get a bit further in your tests.
