A quick catchup on X-Plane.
The latest release of X-Plane Global Scenery (for X-Plane 9) has made all the difference in the world to the spiky mountains - they are no more - they're now good and accurate (Fiordland was not flash in Version 8, now it's beautiful). The price of X-Plane is about NZ$120 (incl. shipping) if you buy it online and get it shipped from the US. Although I'm a member of this forum, I'm an X-Plane customer (as I run Macs, I can't even run MSFS/FSX) but I can use the scenery posted here thanks to a conversion tool I'm experimenting with. X-Plane is as barren with respect to airports as the shipping version of the MS flight sims, so the work of the NZ FS community here is very much appreciated by me too!
In regard to the X-Plane community - it's
very active. There's much less scenery available to X-Plane users than MSFS/FSX users, but probably more aircraft (
www.x-plane.org), most are free too - although the eye candy isn't usually as good. X-Plane went through a major scenery system update in version 8, and the tools are only now maturing (version 9 is 100% backwards compatible). The good thing is that the default Global Scenery is so good, there's little demand for add-on meshes like those from Geographix.
X-Plane has had full support for 3D (virtual) cockpits since version 8, the AI is constantly improving - although not as good as FSX's, and version 9 now includes reflective water and 3D trees all over the place.
Other things worthy of note are that all aircraft, including AI ones, fly with the same flight models as user controlled aircraft. This means that when you fly next to a refueling aircraft for example, it's bobbing around just like you are! X-Plane has combat (since version 8.5), although it's rather rudimentary, nothing like LOMAC. Combat is excellent for WWI and WWII and Korean era dogfights though - it's designed around a Red Flag type training scenario, with no actual damage, just smoke (plus engine failures in X-Plane). Joystick buttons can be user-programmed to control almost any part of the sim (and the keyboard controls are 100% user manageable too - you can even make new controls).
X-Plane 9 uses multi-core computers to the full. The first core runs your plane (graphics + flight modelling). The second core looks after most of the scenery, keeping things as quick & fluid as possible. For a long time, X-Plane has used DLLs in a plug-in format to extend the sim. This makes a large number of extra things possible, like custom FMCs, links to hardware, and more.
