I find that Linux provides the most CONSISTENT performance, since FlightGear supports multiple threads under Linux (./configure --with-threads). I use this so the page build rate does not get degraded by the loading of scenery. I do build under both Windows (9x) and Linux and see very similar FPS values. I would go with the compiler environment you prefer. If you prefer an IDE, you may want to use MSVC under Windows. I don't know if you can build FlightGear under something like KDevelop.
