Flight Simulator X or 2004 ++?

Let me explain with respect to the particular security. I owned the 2004 and to be honest, from the images of the Flight simulator X there was no photo needed change! So here's my positive findings:
-Of News for aircraft, graphics, few things about the workability and certainly better explanations and missions.
Here the negative:
- The graphics that go very quickly to slow down your computer (I have a rather good) and when you push a bit the graphics is slow, I expected small friendly innovations like people who ride the activity in airports or even see what realistic airports, none of his.

So in conclusion what is Flight simulator? it is simply an indirect copy of 2004 unless they have improved things and fortunately the motor of the game as the planes .. So naturally hesitant to know that 2004 is also good, if you're into the idea of a "simulation" after for lovers of good civil aircraft reactors and all the most modern things, we must proceed to the flight simulator X. Then 3 star not 2 because it stays fun for hours without problems and not 4 because it is too generous.
