I enjoy AH, but I also enjoy playing around in GA simulators as well.
So I've had FSX for years, got a few add-ons to make it pretty, and a bunch of GA planes I like on it. But I have a couple things I don't like on it.
First thing is I've never been able to get FSX to run smoothy on my system. I can run AH with all the sliders up just fine, I've played a couple racing games with far better graphics and they run smooth, but I've never been able to get FSX to not be a little jittery. Second thing is the flight modeling just feels wrong, like the planes are just mushing through super-duper thick air or water almost. The two planes I can compare FSX to real life is the C172, and Piper Supercub. In both cases the FSX flight dymanics seem off to me.
So the other day I downloaded the demo for X-plane 10. The scenery and graphics seem on par with stock FSX ones, but run soooooo much smoother. Also in messing around with the 172 in X-plane the flight dynamics feel a lot more realistic as well. Also it seems to have a huge freeware community for add-ons, plus the advantage of continued support (FSX is long dead as far as MS is concerned) and it's 64bit. So I was all set to jump ship and order X-Plane 10. When I hear about Prepar3d....
So apparently Lockheed Martin bought the source stuff for FSX from MS, worked out all the bugs so it runs smoother and updated the scenery and graphics and called it Prepar3d. what I haven't been able to figure out is if LM changed the flight modeling at all. So now that's another option to consider.
But here's the kicker, the EULA for Prepar3d from LM specifically states that it is not for "personal consumer entertainment." They do have an academic version of the license for $60, but they state it is only for K-12 and undergraduate students or teachers. For other use like "simulation" or "learning" for anybody else they sell a "professional license" for $200

Also they do not offer any demo.
I think I'm ditching FSX for sure just based on the way it won't run smooth, and the lack of current and future support. So, should I get X-Plane 10 for $60, or get the academic license of Prepar3d for $60 (even though technically I should get the $200 license..) I mean I don't think Lockheed would come after me or anything, but then again I'd be technically violating the EULA... But without a demo I don't even know if I want Prepar3d...
Lastly, I'm also thinking of Oculus Rift support (seems to me like that will be the near future in flight simulators.) X-Plane has stated that they will have Oculus Rift support. Don't know about Prepar3d, and of course FSX won't since it's a dead program.
Any flight simmers here have any experience with either of these programs? Thoughts?
