"Upgrading" from FSX to FS9

[Jared]

wise choice! I had fsx sitting on my pc but hardly ever used it until I upgraded my pc a few weeks ago and I'm finally able to get in and fly smoothly in fsx with all settings maxxed out

I am another one of those people who "upgraded" to FS9.
I was not able to run FSX at all for a long time, and when I finally got a new laptop it ran fine, the same as FS9 did on the old laptop.
The problem is, I love HD airports and AI traffic. In FSX if I tried to fly into any medium or larger airport with add-on scenery and AI traffic then there was really no point in flying.
With FS9 I can turn all the graphics settings up, install every WOAI package, and fly into areas like NYC with Aerosoft Manhattan and the AI traffic realistically busy at JFK and LGA and have no problems at all with frames.
With some environmental textures (HD Clouds!!!  ) FS9 can clean up pretty well. The only places where I REALLY miss FSX is water, gliders, and aircraft carriers. Everything else is great.

I built a new computer a couple months ago, and can finally fly FSX with settings turned up (almost all maxed) and generally am getting 20-25 FPS in most cases. Of course, as of now, all I have is the stock install. No addons (aircraft or scenery) whatsoever.

I keep going back to FS9 though. FS9 naturally runs a lot better on the same computer. With REX for FS9, and all my aircraft addons (both payware and freeware) I just can't step away from the modded FS9 experience. REX really brings FS9 up to FSX levels. I'm still really happy with FS9. If anyone is have performance issues with FSX definitely look into FS9. I highly recommend REX for FS9 though if you're going to "upgrade" to FS9. If you dont want to spend the money on REX, there are other freeware scenery addons.
