Immediately after uninstalling the unregistered version of FSUIPC 95% of my wind problems I've been having lately disappared. Now I only have small annoying gusts every now then which is normal for FSX. Before the uninstall I got extreme wind fluctuations up to a range of 80kts that would throw my PMDG 747 around like a ragdoll. At cruise level it would violently drop to almost stall speed or go into overspeed several times every 10 min. It's also important to note that I did not have any problems like this before I installed FSUIPC. What in the world is going on here, why is FSUIPC causing this? I can't fly the VRS F/A-18 without it, so what do I do?

If You are using ASE DWC then unregistered FSUIPC interferes with data being sent via Sim Connect resulting in very strange winds behavior leading to s-turns, air speed drops etc (I hope this makes any sense in English... ). If you are not using ASE or any other weather addon, then this might be just a coincidenceHere are my videos showing how unregistered FSUIPC interacts with ASE DWC and PMDG aircrafts: nr1, nr2. Of course this applies to all aircrafts, because its disturbing whole weather. Removing FSUIPC removes those problems permanently.

I don't have ASE, yet it still behaves this way. Thanks for the help, but I suspect there's not much that can be done. I thought FSUIPC was supposed to fix stuff, and instead it does the opposite. I'm gonna check out the FSUIPC forum and see what they have to say.

I wonder why nobody on the FSUIPC forum is reporting this?

The thing is that FSUIPC is necessary for the communication between FSX and several 3rd party add-ons, so not having it seems like a no-go for many people (me included)...

Yes, I need it for my VRS F/A-18 so I have to get it to work somehow.

I'm having exactly the same kind of problems you're having in your videos, but as I said I don't have ASE installed. It's obvious it happens even if you don't have it. But PMDG uses Sim Connect as well, so maybe that could be it?

I watched your two videos. I couldn't see any detail in the first one, but I could tell from the speed tape that your speed shifted around. The second one also showed wind shifts but I would not have known that you have ASE or FSUIPC except that you told me. I have seen exactly the same wind shifts every time I used real world weather in FSX since the day I installed it. Default aircraft or add-ons, REX, ASE or FSX weather engine, with and without unregistered FSUIPC. The only known cure has always been registered FSUIPC with weather damping to 1 knot/degree per second. I am sorry, but nothing you have shown me says this is anything other then the long known about "FSX has crappy weather" issue.

I think you're underestimating the severity of it. How do you explain what happens when I install and uninstall it? The problems begin after an install and disappears when I uninstall. Without it I'm back to the normal "crappy/annoying" FSX weather where you get sudden gusts of wind every now and then, but nothing remotely close to what I experience with FSUIPC installed. What is that?

Hi Paul,I'm flying PMDG aircrafts (J41 and MD-11) for over 1 year now, and I never ever have any wind shifts with ASE DWC when FSUIPC is unisntalled, the only reason why I tried to use that app are small addons like AISmooth etc, but since they are not essential to play FSX I can live without them and without unregistered FSUIPC. So how is it possible that I have made few hundreds flights in PMDG aircrafts without any problems and the only ones when anything happened to the winds were those with FSUIPC installed? I bet since you have registered version you never bothered to check out how unregistered affects sending data by ASE DWC, so maybe try it for your self?Ah, and reason why I don't post in P Dowson's forum, is P Dowson himself (I assure You, he is already aware of this), but you can read HiFi forum, even they start to admit that unregistered FSUIPC and ASE DWC don't work together, as I mentioned before this issue came out when they added some RC4 support. You can even read about it in FSUIPC change log (maybe it was fixed for registered version, but not for unregistered):

29. FSUIPC4 now contains facilities to obtain weather from Active Sky (ASE build 638 or later) in response to weather requests from applications. This is automatically done if FSUIPC detects ASE running locally in DWC (Direct Weather Control) mode, but it can be made to do it even in normal weather modes by adding:UseASEweather=Yesto the [General] section of the FSUIPC4.INI file. Alternatively you can prevent FSUIPC4 using ASE at all by setting this parameter to 'No'.[Note: In version 4.648 the ASE interaction was moved to a separate thread to avoid any possible interference with normal FSUIPC and FSX activities, then, in4.649, the way certain offsets were updated was changed to more suit what Radar Contact seems to expect when requesting weather. This latter change was improved yet again in 4.651 to eliminate a timing glitch which could allow Radar Contact to read the wrong weather].

Now I'm going back to my perfectly straight flying aircrafts, with ASE DWC and without FSUIPC Regards,

I asked Pete about PMDG using SimConnect and wether or not that might be the problem, and here's what he said:

Possibly. I do not use PMDG aircraft but from what folks have said I know they are extremely sensitive compared to others, and there could be timing issues I suppose. Maybe, on a less powerful or more overloaded system, the additional loading on SimConnect of having FSUIPC running too makes the aircraft's timed computations for A/P feedback control go awry.However, there are a huge number of users with both PMDG aircraft installed and also running FSUIPC. In fact many of them use the macro facilities in FSUIPC to gain hardware button and switch control over much of the PMDG cockpit. So all in all I really don't think it can simply be due to FSUIPC's normal quiescent interface actions when unregistered -- it is doing far less then.You do know you can use the Logging facilities in FSUIPC even if it is unregistered? Try checking the Weather logging. You'll see it reads the weather regularly, so that it can supply such data to anything which asks. But unless you have something writing weather through its interface, you won't see any attempts on its part to change anything.RegardsPete

Yeap, the only problem is, that I can reproduce "data block" even with default Cessna, but at least he answered You nicely, thanks for posting that

Hei Emil,As you know, I've been having the same problem you're describing. Though I did not experience any wind shifts at all when running FSX without FSUIPC (or any other addon).However, a few days ago I cleaned up once again, to try the same experiment once more... and today I suddenly had the same violent wind shifts as I used, still running onlyFSX and no addons. Explain it anyone who can, but I cannot.. The only thing I can say, for me FSUIPC is in the clear as of today. I have no idea though, how I could fly for so long without anywind shifts (two weeks), and then suddenly today being thrown around like a leaf in the wind. And that is with the default CRJ700.. It was more or less constantly "chasing", changingfrom almost one second to the next.. Most changes not more than 5-10 deg (speed the same), to extreme changes of 180 deg.I guess it only proves the unpredictibility and complexity of the wind problems with FSX. I find it very strange Microsoft never bothered to fix it, or even create a smoothing functionthemselves..Another thing I don't understand is why the winds should change like this if it is because of inputs from different weather stations. Even if an input changes from one weather stationto the next in a blink, upper winds don't really change very much. As most of you probably know upper wind systems spread over huge distances, and values shouldn't really differvery much from station to station (at least not with stations relatively close to one another - which they are unless over the seas or sibiria.....)?I'm thinking some sort of corruption of the data happens somewhere? Anyone knows?Geir J.

In default weather winds can shift from for example: 180 and 30kts deg to 270 and 90kts instantly, thats why they are interrupting autopilot and are causing aircraft to be unstable. Registered FSUIPC does the job of smoothing those shifts, and with ASE DWC you don't even need any smoothing :)
