I think people expect too much. The simple fact is that FSX will have an expected life span of at least three years. So it's got to be designed to stretch (at maximum settings) a PC from 3 years into the future. How many games run well straight out of the box on a system close to the minimum hardware requirements? In my experience, none. You have to turn the graphical settings down, and then it maybe doesn't look as good as the previous versions. (Midtown Madness 1 and 2 spring to mind - detailed textures and detailed vehicles, shadows, pedestrians, etc. would slow them to a crawl, even on a decent system of the time).
I don't update my system like I used too. Apart from the drives, it's firmly 2003 technology. I can run FSX with the VFR scenery at 30fps with the supplied aircraft, and maybe 15-20 with addon aircraft. But even at 15-20fps, it still looks good, and smooth enough to use. And to be honest, that is all I expect from new software on a 4 year old system. No point me complaining about it! I'll probably update to DX10-compliant hardware sometime later this year, and I'm sure I'll enjoy it even more then.
Of course, it's far from perfect, and hopefully the patch will address some of the issues. But I don't think it's bad enough to be permanently condemned at this stage.
