Actually I want the resolution to be able to be changed anytime in the application. So the user starts the application, finds that the the application runs a little slow, changes some settings for detail and resolution, and now the application performs at a good rate. And a smart application would be even nicer where it tests the users machine and automatically configures this stuff for them (but still allows them to change it). > > I see.

Because if you compile your code on Linux/BSD/Unix/etc. and expect it to work the same on every platform, it doesn't (works on Mac and Windows though). So at least including the Linux/BSD and others that support X.Org is a little better than not supporting any at all. Currently OSG just silently fails when making this call, which you could still do for those platforms that don't support the RandR extension.
