hi guys,if i buy REX, do i still have to use FSUIPC to smooth winds?cheers

That's kind of debatable. Since REX can perform icing and turbulence effects, and FSUIPC can do that too, I presume the deciding factor is if you want either FSUIPC or REX to perform those simulated effects. I would guess that if you have FSUIPC do the icing and turbulence, and don't select it in REX, then keeping FSUIPC's smoothing would be the way to go, as presumably it would work in concert with the other stuff, which is what I've done because it seemed a bit more logical. Trouble is, I use ASE too, and that has options for such things as well. Still got my own personal jury out on that one LOL Could be worth giving Pete Dowson a PM on these forums to see what he has to say about it, since he's the one most likely to know for sure. If you get a definitive answer, I'd be interested to know it too.Al

I do a lot of support for REX and here is a quote from me in the REX Support forum. It is a reply to a customer asking this very question. The thread was titled something like "Final Verdict on Wind Deal""For me registered FSUIPC works wonderfully. In fact, it works so well that I find it hard to believe that people seem to have these equivocal results. For me now, the ONLY wind shifts I get...ever...are when the weather updates. For some reason this new data seems to get injected past the point where FSUIPC can smooth it and so abrupt transitions can occur here. But otherwise...I now run with turbulence enabled in REX and supress turbulence unchecked and it works great, even with the PMDG 747X. I can't say enough about it.Comments that REX doesn't use FSUIPC are completely irrelevant. REX injects the weather via Simconnect, then FSUIPC registered somehow processes this data after FSX does whatever it does from Simconnect and then that FSUIPC processed weather gets rendered. So, whatever winds etc. you are now seeing, will get further smoothed by FSUIPC before appearing in the game. Bad wind shifts are converted into a time averaged change at 2 degrees or knots/sec (my setting) and so you can see overspeeds and underspeeds, but they come on slowly and the aircrt has time to react to them.The difference is night and day. For example, I can now fly the PMDG 747 in a 100 kt direct crosswind with turbulence (wind speed oscillating up and down 10 kts/sec, which is how FSX emulates turbulence). Before FSUIPC this aircraft could not handle this at all without banking at 45 degrees back and forth and was basically unflyable. Now I just have maximum 5 degrees bank if that. Check supress turbulence in FSUIPC and this oscillation instantly goes away. Uncheck it and it might return. This is what is known as random turbulence, which I have enabled in FSUIPC it works so well. For the smoothest ride, uncheck REX enable real wind and shear option and check Supress turbluence in FSUIPC.Another thing that has been completely eliminated by using FSUIPC is what I call Flucuation. This is where the wind speed AND direction flucuate back and forth 1-2 times/second as if two different wind conditions are fighting each other with one more dominant than the other, then switching to the other. Sometimes these directions can be 90-180 degrees apart and 10-60 kts different.One last thing that has been eliminated is the following: Often during descents, the upper level winds of let's say 290/92 kts at FL350 would suddenly return at 7,000' where the wind was say 340/7. This would continue for anywhere from another few thousand feet to all the way to the runway. Imagine trying to land with a 60-90 kt corsswind. Very frustrating. The same thing would happen during climbs as well. At 28,000' where the winds might be 030/45, the ground level winds of say 180/7 would suddenly return, dramatically altering the climb. Then a 1,000 or 2 feet later the upper level winds would return after the aircraft already dealt with the previous wind shift. Climb hell is what that was. FSUIPC has completely eliminated this.Needless to say, I highly recommend registering FSUIPC and learning how to use it. If you already have it registered from FS9, it is only 12 euros to upgrade it to FSX."For reference, here are my FSUIPC settingsI have since flown over 1000 hours using this setup with REX2-SP2 and various payware aircraft and only under the most extreme conditions of 100 kts +/- direct crosswind have I had to turn off turbulence with the PMDG747. Sorry, I don't have the MD-11 but I imagine it is the same.Hope this helps

A while ago I registered FSUIPC just for the wind smoothing and never looked back, I also have REX2 (bought it after I registered FSUIPC) but I leave FSUIPC to deal with the wind smoothing.

To toss in my own $.02 (0.0156443 EUR),,,FSUIPC (Registered) is much more than something for wind smoothing. If you want the ability to fine tune your controls, then it is a MUST have. Of course if you have a lot of other gadgets (cockpit builder stuffs), then it's a no brainer as well.REX2 has the best textures on the market in my opinion, and as I've stated before; It is the one addon I wouldn't go without. Seriously, I would throw away my FSX if I didn't have the cloud textures, and skyscapes!ASE is my weather engine of choice. REX2 needs no more praising, and I could write a very lengthy article on how great it is, but it is their 1st attempt at a WX, and ASE offers a whole lot more.FSUIPC is better at wind smoothing then REX and ASE. Even ASE's developer will tell you to use it for the smoothing if you have it.*Edit: When I 1st read this I thought you were not wanting FSUIPC at all if REX had smoothing capabilities. Now that I see that is not the case however, I think I'll leave it as is to help other passer-bys.

Hi just to add my thoughts to this thread i got rex2 as well and still found out the wind problems using the 747 and the md 11 since puchasing a reg copy of fsuipc i found out that now i have no problems with wind changing directions and no wind fluctations in wind strength at all. So if any one who has trouble with the wind problems and hasnt got a reg copy of fsuipc i would recommend in getting it. Since i wasnt to sure b4 but since getting it i havnt looked back at all

Different products, really. I use REX2 and only recently started using FSUIPC (long story on why it took so long, I know a serious simmer without FSUIPC is like an Irish bar without Guinness) As the first comment noted, you will, when the weather updates, get some crazy shifts sometimes. But, at worst, the airspeed will change dramatically and the bird will bounce up or down as it restabilizes. Unless you have the "detect damage" setting on in FS, this will calm down in a minute or so while the sim cathces up.

A few flights for me went from stall to overspeed multiple times in minutes, thats when I had enough and got a registered version, problem solved.

FSUIPC + WIDE FS = awesome. I cannot imagine FSX without either of those two programs. Makes me laugh when I think back to when I first started flying on FSX with no joystick and throttle, no weather add on, no payware aircraft...its like paying to look at a b+w photo copy of the Mona Lisa.

I don't know about REX but ASE does some items that can provoke errors with FSX. ASE using SimConnect weith DWC on for smoothing winds and visibility forces Global weather mode on. This means that the FSX world (and FS9) see the same weather at airports as around your aircraft. The ASE manual on page forty states the disadvantages of Global weather writes such as incorrect FSX ATIS reporting. I imagine this would also cause weird AI behavior.The airport weather will change in global mode as you approach your destination. AI behavior beccause of pattern smoothing may not reflect your ATC runway assignment by the time you arrive. In addition as I interpret the ASE manual Global writes may only update separated by several minutes.(FS9 users do have the option of ASE smoothing without Global weather mode being forced with DWC because it uses FSUIPC to do its wind smoothing.)If you decide to turn off DWC in ASE then in the weather tabbed pages of options you can then select other than global mode and specify effect ranges in nm relieving the problem of incorrect weather changes as your aircraft approaches your destination.Of further note, in the ASE manual there is a long section dealing with "turbulence sensitive" models including PMDG products and how to correct for that.I downloaded the ASE manual because of complaints by RC users about incorrect runway assignments and AI conflicts. In addition there were complaints of RC performance degradation in ATC communications. Some users have stated other application problems as well. It appears that turning off DWC and Global mode relieves CPU workload as reported by ASE and RC users. Those users use FSUIPC for visibility and wind smoothing.If REX requires using global mode for weather with FSX I imagine similar problems can occur.I use AS6.5 with FS9 and global mode is deselected. Weather at the destination is reported near the METAR parameters when 40 nm out when contacting approach as well as getting destination ATIS. RC's runways assignment method gives first priority to AI patterns followed by various weather and runway properties. FS ATC is similar.
