Flight Simulator 2004
To determine the in-game performance in Flight Simulator 2004 we used a recorded video of a flight in the scenario "Hong Kong at dusk". We used the standard quality settings with unlimited frame rate and trilinear filtering.
The GeForce 6600 GT delivers good performance in Microsoft's Flight Simulator 2004. Surprisingly, the X600 XT also keeps up remarkably well, outpacing our emulated vanilla 6600.
