Hmmm
Well I check this forum periodically. A very interesting topic to be sure.
Personally I am going to develop predominately for FSX only. I would like the develop for FS9. But realistically, FS9 is slowly dying. For all of those who might disagree, I would challenge you to think for a minute. How long is it really going to be before most people switch to FSX exclusively. With better pc's and graphics cards technologies being developed constantly. FSX's popularity is growing quicker than you might think. This time next year, I bet most fs pilots will be using FSX. FSX with all its flaws from the development point of view, is a thousand times (a figurative statement) easier to develop for than FS9. The performance of FSX has been improving with each service pack. SP2 made a HUGE improvement on my game pc. It is unfortunate that FSX was not more developed when it was released. We do not even have full DX10 support/features in FSX. However, it is a work in progress. The real clincher for the widespread use of FSX is going to be a 'stable' server and client released to the public. I am not a fan of Game Spy nor am I fan of limitations for my choice of servers to fly on. So the person that can develop a multiplayer server and client (that is stable and better than DirectPlay based software is going to take FSX to the next level)
As far as backwards compatiblity with FS9, why bother. I like FS9, but FSX and FS9 are two totally different species when it comes to development. FSX is the future, it needs some love that is for sure, but its easier to develop.
Would I backwards develop software for FS9? The answer is no, by the time my software is released to the general public, my money says most simmers will be flying with FSX.
Ok some other points. I bought Vista the day it was released. DX10 requires Vista. I adore Vista, it lives happily on all my pc's. For all the Vista haters out there, well I feel bad for you, you are missing the wave of the future. Technology moves on, and it grows with time. XP had just as many issues on its release, but there were half the pc users at the time, hence less exposure to its issues and the awareness and publication of them. I remember all the games I could not get to work on XP.
Well the FS9 to FSX transition is no different.
I am not going to waste my time developing for old direct x version, old os versions, and FS9.
From a commercial perspective, there is not much economic sense developing for FS9 or XP or DX9
Do I still fly with FS9, the truth is yes. But only when I fly online. There are no standalone FSX servers that are not based on DirectPlay, personally I am sick of DirectPlay based multiplayer software. There are also no 'FSNavigator' type software for FSX, etc the list goes on, hence my argument above.
Vista, FSX, DX10 rocking for me.
