I go to their website all the time but I just can't understand what the program does. Does it like change key assignments? What else does it do? Thanks

FSUIPC interrogates FSX (or FS9) and extracts the state of a wide range of parameters, allowing other add-ons to interact appropriately with the sim. It can also be used to calibrate joysticks and define keys. Enormously useful and updated for many years, it is widely used in the flight sim community. You can install the free version or pay a small fee for the registered version with greater functionality. Highly recommended.Cheers,Noel.

FSUIPC4 is theSwiss Army Knife of FSX!Download the FSUIPC4 User Documentation, then take a look at (skim) the following documents:1. FSUIPC4 User Guide2. FSUIPC4 for Advanced Users3. FSUIPC LUA Plug-Ins.Also take a look at the LINDA User Manual (LINDA is made possible due to FSUIPC's implementation of LUA).Cheers,- jahman.

HiWhen you don't have FSUIPC you can live without it but once you have it you cannot live without it.Very useful for keys, joysticks, throttles, switches, buttons assignements or calibrations, just to name a few possibilites. Highly recommended.

For me, it's what finally fixed FSX.

Buy it, you need it. It's just that simple

Buy it, you need it. It's just that simple

+1If you're a serious simmer AND you don't want regular G3D freezes and CTDs, then FSUIPC is the one application you simply must have (IMHO of course).It makes so many other addons SO much more enjoyable AND FUNCTIONAL!

Let me post something for some needed balance...

Buy it, you need it. It's just that simple

Well, that's too simple. Dangerously simple, even. I think it's better to say 'Buy it if you need it.' Because that's how it is. You can't know if the OP really needs it...!!! If he only has a simple joystick and (or!) doesn't care about different controller setups for different aircrafts, he would be spending a lot of money on 'just' a wind smoother or an autosaver... and maybe the OP doesn't even need a wind smoother and an autosaver can be found elsewhere for free...@linux731: jahman advice is the best and it will lead you to the only real answer to your question: read the manuals (page 3 of the user guide gives a good overview of the possibilities of FSUIPC) and see if you need it: if you do, buy it today, if you don't need, don't buy it.P.S. Something that's not in the manual yet: the latest beta of FSUIPC also helps to prevent specific g3d.dll appcrashes: if you have frequent appcrashes, give the beta a try (you can use it with the unregistered 'free' version) and if it stops your appcrashes, buy FSUIPC: not because you have to, but because that would be the right thing to do imho.BTW I don't own FSUIPC because I don't need it (no need for its controller options nor for its wind smoothing nor for its autosaver not for the appcrash fix: I don't feel the need to spend money on something I don't need only in order to be regarded as a serious simmer. )

Good points. I've had add-ons in the past which have automatically added the free version to my FS9 or FSX set-up, but they've gone and currently I don't have it, because I don't need it. It's that simple...

I'll stand my my comment. Buy it, you need it. Period.

I don't have the registered version yet and have never missed it... but it does a lot of cool and handy things for FSX.

HelloSome great examples in this thread of why Pete should have put the g3d fix into the registered version only.

I have had FSUIPC registered for years and would never fly without it. The functions that is provides go far above just joy stick controls, which by the way I use on the Level D 767. By far away Pete has done more to make FSX and FS9 so much more reliable. Pete's knowledge of the inter workings of MSFS are so vast that not having the program is almost indefensible IMHOBob

So it changes key assignments and fixes some CTD issues?

helloDid you read the documentation ?.It does very much more than that and I personally could not use my sim without it.Take some time and have a good read of the excellent manuals and be amazed.Probably the best Fs addon ever, If Pete does not update Fsuipc for Flight! then I doubt I will even buy the sim.
