To improve FSX performance, I use the utility FSX Booster. For FSX booster to work, you first open FSX Booster, and then click "Fly Now" to run FSX. However, today I purchased REX, only to find that you must do the same thing. I tried running FSX through FSX Booster, but that only resulted in an error message saying REX had stopped working. And considering REX isn't going to make things any easier on my computer, I really want to be able to run FSX Booster. Is there any way around this?Edit: And is there any way just to load REX without entering a flightplan? Obviously I pretty much always load a flight plan, but I'm currently just trying to get a good look at REX. Basically, what I'm trying to find out is if I can have REX load its textures and then proceed with FSX as usual (with FSX Booster). And what if I want to load one flight, fly that, then load another? Since REX loads weather by your location, do I need to re-load REX and FSX?Thanks,boeing247

No, you don't have to start FSX through REX. You can though. Just set your textures and things in REX, close it. Start all boosters of yours and then FSX.

That's a relief. What's the exact procedure? I thought I had done that, but when I loaded FSX, everything looked the same, and when I tried to load it again, REX crashed (and again in my subsequent attempts).And do I have to load textures for every area I visit while FSX is open?(by the way, I clicked "fly now" and it's been loading for several minutes--does this always happen, or is it just because this is the first time it has loaded the textures?)

I must admit I've never ever pressed 'fly now' in REX. :( So the sort of procedure for me is to pick some themes in REX once a while. May be mood driven or wannabe scientifically picked to fit the region and climate. For the nice clouds, I may use the flight planner and let it pick some items which fit to the actual weather on the planned route. Then it injects its stuff into FSX. After this, REX interface closed.Then start FSX and the REX weather engine if needed. So for you, that would be the time to start the booster rockets.

Okay, thanks. Despite the program's pretty user-friendly GUI, I've still managed to confuse myself--I'm sure I'll figure it out.My one question, is, however, is there a way to load real-world worldwide weather and then close REX and start FSX normally? I was able to load weather into FSX and then start it with FSX Booster, but the weather was the same everywhere (and I chose airports where I knew it was raining in reality, but as it turned out they weren't in the sim.)And like the term "booster rockets". Clever!Thanks!

They eat a lot of fuel. ^_^To be precise, you go the way of 'flying now' and feed the flight planner with your departure and destination. In the process it will download the current weather and then allows to set the clouds accordingly. On the later part, when FSX is already running, you can fire up the REX weather engine (you can also set auto start) and then get the weather in FSX.So the first part is to just set the right cloud textures, on the preflight. The other one then is the actual weather data while FSX is running.

I do it the simple way.I install the REX textures and then just use REX for the weather. I don't install "weather related textures". I click cancel in regard to that option. I like the textures I have so I leave them that way.I also shut down REX once the weather has loaded.Once REX textures are installed, they stay installed.As for your "booster" utility, does it really work? I'm dubious, I would say if you did a proper test, you would find not. I've certainly never needed any booster utilities.

So if I want to fly somewhere else, I'm going to have to load the textures again?Basically, what I'm asking is, is there a way to load worldwide real-time weather textures into FSX, then start FSX and fly as usual?

As for your "booster" utility, does it really work? I'm dubious, I would say if you did a proper test, you would find not. I've certainly never needed any booster utilities.

It does give me a few extra frames, and allows me to better tweak FSX. That being said, it can be a real pain in the next sometimes. But yeah, it helps.And does REX usually take 5-10 minutes to load weather (not the weather engine, when it's loading and colorizing textures)?Also, I noticed that there's an fsx.cfg file in the REX folder. Which .cfg file does FSX use? And are they linked in any way?

Now I see your point. Ok, for the updates on just the cloud textures (that's the weather dependant stuff, the rest is fixed) you have to uncheck all the other texture update options like sky textures, water and so on. This will improve the texture loading time a lot and also avoids that it writes the complete texture set to your disc on every weather update.If you want to change the other textures because you like to try a different sky set, enable the options again. You can use presets there, so this may avoid some clicking action. If you want to have 'accurate' clouds every time and depending on the weather, you would have to update those clouds every time you start FSX.But you may of course leave them as they are for some days and when flying to the same spots in the same season. REX can therefore help you with the static cloud system of FSX, but it needs to update those things when FSX isn't running. With the tweak from above, the clouds only take a few seconds though, so maybe you go for that. I don't always do.REX may edit your fsx.cfg on the 1024 to 4096 value at TEXTURE_MAX_LOAD=1024. I think that's the only change it enables after running the REX UI. What you are seeing there may therefore be the backup the REX UI sets up. The valid fsx.cfg is at C:\Users\boeing247\AppData\Roaming\Microsoft\FSX.

Okay, thanks. I looked into it more today and found that if I just load the weather into FSX with the REX Weather Engine window (WASys), it loads real-time weather for the world. Is that enough or do I have to do more for whatever reason?

Sounds like you are ready to go. Make sure to run the latest patch (the UI states the version) and maybe get the free Overdrive pack, which adds a ton of texture sets (and installation time).For the upcoming rework 'Essentials', you'd have to register at their forums and place your order number in the signature or something. They then verify the account. This should enable a later download of the updates, when they are available. I hope I did get that right.But I'd say flying some routes now is the best idea. Just explore the difference and the weather. I think the weather engine receives a major rework with the upcoming Essentials. They've posted some feature descriptions in the forums.

Okay, I'll check my version, though I purchased from SimMarket, so I already have the Overdrive pack. Is 2.5.2010.1027 still the latest version?

Yes. I'd have to check the forums, but that's the one I'm running too. Means it's the updated Overdrive version and therefore current in my eyes.

With the old REX (2.0), when I started FSX, it loaded the REX weather engine. Is there a way to get 3.0 to do that?  

With the old version of rex2 you didn't need to open up the control panel , but with the new version rexe  you have to.
