Well, on Windows SDL_WM_ToggleFullScreen does nothing in SDL 1.2.11 . So to
change to full screen mode, I have to call SDL_SetVideoMode with the
SDL_FULLSCREEN flag (or not, to get a windowed mode).
Same thing (even more so) for changing resolutions.

I only mentioned these two cases (scene graph has changed versus not) because
one case is easier to reload than the other. If nothing has changed since the
last load, I can just reload the same thing. Otherwise, I have to see what has
changed, save it somewhere and reload it so that OSG recreates the textures and
display lists etc. I believe that's easier than your following suggestion:

That may be more complex than I'm willing to tackle. We'll see if I ever need
something like that. I currently don't know enough about OSG to go poking into
the internals and potentially expose something that was only used internally
before...
For now, I think I'll just leave the full screen and resolution options in a
config file (so restart to see the change) and maybe in the game's main menu
(so there is no level or anything loaded when it happens, and then the
reloading after mode change is simple).
Thanks for the discussion, it was very enlightening.
