At the risk of sounding flippant though, the graphics are still not great. Now, I absolutely understand how computationally demanding flight simulators are, but I can't help but feel that Microsoft oversold the graphics capability of FSX. As someone noted in the thread, for me, this means there's still some suspension of belief required.
I just cannot wait until we have a flight simulator that has graphics comparable to non-simulator games. I think that might actually compel me to spend the $10k (or however much you need for the compute power and peripherals) and invest the time in such simulator. Maybe when I'm retired, I will get to experience the dream of flying planes in what feels like almost another reality.
