I’m using P3Dv4.1 and SODE 1.5.3 and I often experience stuttering issues at airports using SODE. When getting close to the airport still in the air the sim pauses for about a second or so.
On the ground I see the same issue but in that case the stuttering/pause is even shorter than a second but instead the stutters are more frequent.
The FPS is fine so it’s not a low FPS issue.
I heard lots of other people are experiencing the same thing so I was wondering if this has been reported in here and if there’s a fix planned in the near future?
Hello
While SODE itself won’t introduce any stutters directly when it is running, it is however possible that the sim is not able to find a SimObject that is requested by SODE and this is usually the cause for stutters, because the sim reacts this way when it can’t find a SimObject.
The mechanism is like this: SODE wants to have a SimObject displayed -> SODE asks SimConnect to load the SimObject (using the SimTitle of it) -> FS tries to look up that SimTitle internally -> If it does not find it, it will probably do a deeper search of it internally (delay, stutter) -> FS stops the search and notifies SODE through SimConnect about this with an exception -> SODE will log that exception.
Usually, you should see lots of SimConnect Exceptions in the SODE.log.
Root cause could be that sceneries that use SODE either haven’t completely installed the SimObject files in the proper directory, or when you uninstall a scenery, the installer forgets to uninstall the control xml file.
When the control xml is still in place but the corresponding SimObjects deleted, SODE will still try to load the SimObjects which are not existing anymore on your harddisk.Please post your SODE.log of a sim session where you encounter those stutters related to SODE to confirm my assumption.
Thanks for your update.
T2G LFPG being the airport with the most SODE jetways included, it is possible that an already packed SimConnect pipeline will shortly congest when SODE instructs the FS engine to inject 200+ jetways at once.
Think of injecting 200+ AI objects into your scene…
SODE is otherwise pretty quiet on the SimConnect channel.I am thinking of injecting objects in chunks, so the load is a little more distributed for FS. Drawback would be a possible “popping-in” of objects, but a couple of NM out of the airfield, this should bother nobody.
I’ll be playing with this idea in the new year and hopefully include that into the next SODE version.
Happy new year!
-JeffreyQuick update:
I think I have found a workable solution by loading the objects in batches. I don’t get any noticeable stutters anymore when the objects are being injected by the sim.
As an additional benefit, I have added checking of the existance of the MDL files associated with the SimObject. If the MDL file does not exist, SODE will replace it with a default object which is a red ‘X’ marking the missing object. This way, the stutter induced by missing MDL object is gone and the user gets feedback of missing objects visually and in the SODE.log.
Let me know if you want to try a beta.
