Question - Networking OpusFSX

Recommended Posts

Stephen - If I wanted to run OpusFSX on a client PC to lower the load on the PC I have FSX installed, can I still use TrackIR?

AFAIK OpusFSX server must be run on the FSX machine, clients can be used to control live views etc, but no, you can't split it off like other products.

Brian - I tried to run the FSXCLIENT.EXE which could inject weather into FSX but I couldn't get TrackIR to work.

FSXCLIENT can only connect to FSXSERVER, which must be run on the FSX machine.

 

Unless something has changed in the last 2 weeks I'm pretty sure what you are trying to do isn't possible with Opus, unfortunately.

Actually, I didn't have FSXSERVER installed on the PC running FSX. Only the FSXCLIENT was running on my networked PC which injected weather into FSX

We consider it more efficient to run the OpusFSX server on the main 'flying' FSX machine so don't provide an option to run it on a client PC. Therefore TrackIR should only be set up the server machine.

 

As mentioned above the client can be used for displaying weather maps and controlling the weather if you don't have FSX installed on the client. If you wish to display views on the clients then you must install FSX.

Hi Cheryl

 

Please clear me up on this.

 

I use another weather program running on a client machine which injects weather into P3D across the network.  It requires the use of simconnect.  I believe LM changed the SDK in v2 so that some programs using simconnect are having difficulty until things get sorted out.  I like programs that use FSUIPC such as Plan-G and others, never any problems with network communications.

 

I am interested in purchasing OPUS for the same purpose but I am not clear if simconnect is required for OPUS to run on the network or if I can use FSUIPC on the server and WideFS on the client to inject weather from the client to the server?  I have read the installation instructions on the website but in my old age I am still a little fuzzy about running OPUS on the network.  I do not need to display the weather on the client but it would be nice.

 

Thanks for your help.

Opus injects weather using a different method, by Dynamic Weather Themes, but issues the load command via SimConnect. All this is done on the main flying server system. You do not need a client system and there is no benefit to generating the weather on the client so we don't do it. The LWE has no impact on the sim and needs to coordinate things such as turbulent motions in real time, hence its best for the LWE to run on the main system. You can set up a 'No Connection...' Type client to provide control and look at weather maps etc. but it does no weather processing.

 

So SimConnect is required on your main system and on the client if a client is used, but its not used to communicate anything. Our own IPC comms software does that as and when needed.

Though it may be tru that it has no effect. You still have to "remember" to start the server before the sim? Im looking at the Opus demo now. Your saying there is no way of starting the weather engine on a client and not have the server running on the host?

I did not state my question (below the dotted line) properly and it should be ignored.  Re-reading your response clears things up.

 

I presume OPUS is compatible with P3D V2?  I am interested in terminating the other weather program I am using and want to be clear.

 

Thanks

 

------------------------------

So I take it you are saying there is no real benefit to running OPUS from a client and running it on the main P3D machine is the desired method?  No FPS impact etc.?

There is no benefit in fact there would be detrimental effect since the LWE provides coordinated support to the DHM and Aircraft turbulence software. What you would save (minimal if anything) by having the weather generated on the client you would more than lose by having to communicate the data and weather file. Unless of course you have a ten year old single core PC. With modern day multi core PCs, Win 7 64-bit, and adequate memory, the LWE has no impact.

 

The software has always been designed to have no impact on the simulator's performance. Of course you should do the usual and try and give the sim its own dedicated drive preferably a SSD, since they are generally not multi access, all the usual precautions really. You will have to install the P3D V2 SimConnect as well but you have to do that anyway unless you are not going to install any Addons.

 

Stephen

 

You should also bare in mind its the sim that tells Opus where you are, which then determines what METARs to download in order to generate the 800 x 800 mile weather map. Other weather data may be needed to generate reports from activated flight plans etc.. OpusFSX has never had any affect on the simulators performance. Slight pauses can occur if you generate weather map data and share a disk drive with the sim, depends whether the sim is trying to access data from the disk at the time.

But, in a single system, there is no way of checking weather maps, temps metars etc unless one minimizes the sim ?

Of course there is.

 

You have the Opus on-screen weather reports, you can run the sim in Windowed mode, or switch to windowed mode, and then view all maps and reports, or install a second monitor and use that.

 

But you can always connect a client system and simply run it in 'No Connection To The Sim' mode. You can then use this to remotely control the LWE, use the LWA Live Weather Assistant to look at all maps, display up to six weather maps separately, open and view text reports for downloaded METARs, GRIB wind and temp targets, flight plan reports, and SID/STARs data reports.

 

The choice is yours. You don't need to network the SimConnects and only need to install SimConnect (which we supply) on the client so that the libraries are present, but the client doesn't use them it just needs them to be installed.

How much information do you need to fly the sim. All that really matters is in the reports especially if you have processed a flight plan.

It is best to run FSX before OpusFSX and if you are using P3D v2 then we have found the opposite may be true - run OpusFSX before P3D v2.

 

OpusFSX server must run on the host 'flying' sim PC.

 

Cheryl

 

Yes it is fully compatible with P3D V2 and the Beta version even has an Enable Volumetric Fog Effect option in the Weather preferences dialog. Set this option to control the volumetric fog and provide excellent fog, mist, inversion layer, and even restricted vertical visibility effects.

 

See our SimForums for details.

I downloaded the demo this morning and installed it.  I am using P3D V2.  I have a default flight of a Cessna 172 at Williams Field KIWA (just a mile from my house).   I start P3D V2 and the flight loads normally.  My problem is that prior to loading OPUS all of the mountains surrounding KIWA look quite normal.  As soon as OPUS injects the current weather ALL of the surrounding mountains turn totally white as if they were covered in snow from top to bottom which is certainly not the case here in middle Arizona.

 

Reloading the flight restores the mountain view to normal until OPUS injects the weather again and the mountains all turn totally white again.

That's an easy one.

 

If you have Volumetric Fog enabled in P3D then you MUST also enable the Volumetric Fog Effect in the Opus Weather User Preferences dialog.

 

If you don't P3D accumulates all the visibility layers (a fault in P3D v2) and produces dense fog where ther isn't any.

 

So either turn both Volumetric Fog effects on or off. When off then Opus will inject the usual visibility layering which P3D cannot handle correctly when its own VF effect is turned on. This is a well known problem with P3D v2 so it might be fixed by LM in the near future.

 

Stephen :-)

 

While you are at it please read the Opus Recommended Practices using the Question Mark icon at the bottom of the weather dialog. That might help you in the demo but the demo is quite limited so it may not matter.

Thanks Stephen, that fixed the problem.  I remember seeing comments there was a problem in P3D V2 with the fog but did not know it would affect OPUS.  Works great now.  Thanks again

You're welcome. Its more a case of the LWE having to accommodate the P3D v2 volumetric fog problem. Hence we have added the Opus Enable Volumetric Fog Effect option to take account of the problem.

 

If you do use the VF effect you will notice the visibility increases too much at altitude, above what would be the VF layer. Nothing can solve this until LM sort the problem out.

 

I generally recommend to use the VF effect if you fly low level VFR and perhaps turn it and the Opus option OFF if you fly high level. But its up to the user and can be down to personal preference.

Hi Stephen

 

I purchased, downloaded and installed OPUS this morning and all works just fine.  It is version 3.37.5.

 

I have a question about the update process.  Your website says "If you have previously purchased OpusFSX and want to upgrade to the latest Release version then click on the Upgrade button and download the OpusFSX.msi file.".  Does "click on the Upgrade button" mean on your website or is there an upgrade button within OPUS (that I could not find)??

 

I tried it thru your website, downloaded the .msi and then ran the .msi file.  I see the version number I am using 3.37.5 stayed the same, does that mean that there was no update available??  I presume if there was a new version it would have downloaded and installed it?

 

Thanks for your time.

Hi John

The Upgrade button can be found on the RH side of our downloads web page,

http://www.opussoftware.co.uk/opusfsi/downloads.htm

At the moment both Release and Upgrade versions are the same 3.37.5, this is usually the case as I generally post betas and when ready generate both a new Purchase EXE file and a new OpusFSX.msi file.

You can also follow our Announcements in our SimForums pages, I try to announce the most important upgrades and betas here on Avsim as well.

Stephen :-)
