I think,Could FSX had a technical problem?

Sometimes I think FSX has a technical issue, Maybe the 85% of the FSs customers are too far away to purchased a Pentium D ,and maybe 40% are using celeron or Pentium 3(In all the world) Microsoft its busisness company,and I still Remember the HUDGE MISTAKEN of Windows ME a totaly failiure ,I just bought my new system and its fast for everything exept for FSX, Its not about "To Make a Game for a Minority Rich people" remember its a powerful businness company,its convinience it to sale more ..
Ok It runed with a little enough to be apresiated in my old P3 with the minimum setting with 6-10 FRPS, I had this same video card wich It help it a lot, I bought & assemble this new machine ,God it runs very fast for everything ,games ,videos,dvd etc,.. ,but exept FSX in a medium low-high 12-17FRPS I wonder why isn't enough considering that MS is a smart busisness company,there might be some technicel issue..Even Intel release a P4 with a serious issues a took out of the market,that's when AMD Athlon Took his place...Remember?
