Microsoft's Flight Simulator X continues the series' long, august tradition of pushing the envolope of PC hardware. Even though I recently upgraded my rig to take on this bad boy, there still needs to be a lot of tweaking done to get things to a reasonable frame rate, expecially when flying low over heavily populated areas.

The good new is, as per usual the massive fan community for FS is busy riding to the rescue with a large number of undocumented lines in the .ini that make a huge difference. My advice is to fly over to the two big fan websites and peruse their forums, your FPS will love you.
