Does FSX Retail perform better than the demo?

Well my guess is that if you are getting low FPS from the demo things would be worst with FSX unless if something else causing your problem...FPS has to do mostly with systems performance and not so much with FS.
Can you please share with us your system specs?

Could be you have too many backround tasks running. Open task manager. Press the tab that says processes, now clib the User Name tab. Delete all tasks that are being performed under your username. EXCEPT EXPLORER AND TSKMANAGER!!

I have the following

- Dual Core Athlon X2 4200+ CPU
- 2gb DDR2 533 ram
- Geforce 7900 GTX 512 mb graphics card
- 320 gig 7200 rpm hard drive
- Dell 24 inch LCD

I can run flight sim 2004 in 1920 x 1200 resolution with full settings at steady 60 frames per second.

When funning the FSX demo, I get 20 frames per second with less than half the settings. It looks terrible, its unplayable. I also have the ltest Geforce drivers. Also, it doesnt seem to make a difference what resolution I use, they all get a similar frame rate from 1024x768 up to 1920x1200

Nice computer! Keep in mind that Demos are never as good as the final product (usually) and that it might still be being configurated meaning that when it comes out it will be configurated to perform as well as possible! Also I don't know if the demo utilises boths cores in the processor.

I can actually get up to 60 frames in 1024 x 768 with very low settings but anything more settings just kills the frame rate

By the way, I had a AM2 single core processor last week and it made almost no difference to the frame rate ween I upgraded, also no difference in FS2004

I found the latest geforce drivers made a much better frame rate difference (up tot 20-30 frames)

It will run, but do not expect great performance. Also, you didn't mention how much RAM you have on the motherboard.
