So I'm at 28,000 ft and I hit a huge weather shift that knocks the aircraft around and the temperature rises to +44C. My speed begins to drop and so does my altitude. I have real world weather set but there's no way that real world temperature is that high at that altitude. My settings are pretty much default. 

 

As I right this the temperature is dropping and it looks like it will figure itself out but what would cause that?

Sounds like you have two sources of weather injection. That would definitely cause all the problems you have encountered. OpusFSX generally provides rock solid and accurate ambient temperatures (OATs or SATs, the calculated TAT is of course always higher than the ambient temperature due to the compressional heating of the air molecules).

 

Make sure you have NOT enabled any other source of weather including the FSX RW weather, that will definitely cause all sorts of problems. Also make sure you have disabled all other weather engines and removed any of their DLLs, the ASN DLL in particular can be pro-active and has been known to cause problems.

 

The OpusFSX LWE has rock solid temperature targeting and does not generate any wind shifts at all provided you follow the Recommended Practices, have FSUIPC4 installed and enable the OpusFSX Dynamic Wind Control (DWC).

 

Make sure you read our Recommended Practices topic or instructions in our Weather dialog. The various on screen weather reports and other reports and weather maps will allow you to determine exactly what the weather should be and also monitor both the targeted ambient winds with the actual ambient winds. With DWC enabled these should never drift more than 2 knots and 2 degrees apart.

Stephen, thanks for the detailed and informative reply. Should I have FSX weather set to User Defined with Clear All Weather Checked? 

 

I have Rex Essential + Overdrive and the weather settings give me three options, none of which seem to me to shut down the Rex weather engine. The three options are:

 

1) Use Real-Weather Data

2) Use REX Random Weather Themes

3) Use Archived Weather Data

 

I have Use Real-Weather Data checked. 

 

Thanks for the help. 

 

Edit: My bad, found the settings for Rex, there's a bar along the right and under Weather the Enable Rex Weather Engine is not checked. However, the section for winds has  Enable Real Weather Winds, Wind Smoothing and Wind Turbulence checked. I guess these are not unchecked when Rex Weather is disabled. I've unchecked these and will see how that works. 

Oh, there's your problem then. You must not run REX as there can only be one source of weather injected. The above will most definitely be causing all sort of problems with the ambient conditions. So please turn REX off. Use it to install your textures and then leave it inactive.

 

As far as FSX is concerned it really does not matter as long as OpusFSX installs the weather since it will place FSX in custom weather mode anyway. But you most definitely cannot have the REX weather engine enabled in any fashion at all.

Some people run up REX first to load the appropriate textures then shut it down. The latest version of REX allows you to specify OpusFSX as the weather engine so that it will load the appropriate textures for the current weather and then shut itself down and run OpusFSX.
