In our game, running in windows 11, custom game engine, FMOD Studio 2.03.08, if I record a large multiplayer battle into the profiler and click through the timeline, the profiler itself slowly becomes less and less responsive. It will get to the point where nothing triggers audio in simulation mode.
I have uploaded the profiler recording as a package to my profile on this site.
Is this behaviour expected due to the large number of events, or is this a bug in Fmod Studio?
Thank you for sharing the profile recording and the detailed information.
I wasn’t able to reproduce the issue on my end using the recording you provided. However, we did address some UI stalls with large profiler sessions in our latest release. Could you please try testing with FMOD Studio 2.03.09 and let us know if the issue still occurs?
Hey,
we’re experiencing the same problem here.
The profiler becomes very slow and almost unresponsive after few minutes of profiling.
We’re on FMOD 2.03.07 , at the moment we can’t upgrade.
Would you mind sharing a bit more detail on why upgrading to the latest version isn’t possible at the moment? We generally recommend moving to 2.03.09, as 2.03.07 is less stable and many issues have been resolved in the newer releases.
Unfortunately, I was still not able to reproduce this issue on my end.
Could you please send us the Studio logs from the affected run so we can dig deeper? On Windows, FMOD Studio’s log files can be found in %HOMEPATH%\AppData\Local\FMOD Studio\Logs .
@amegliofrancesco ( cc @li_fmod ), I’m experiencing the same thing. Nothing is wrong on the project itself, so I assumed the amount of data for a profiler session was too much to handle over time and I’m containing my profiling sessions to a 2/3min span, or eventually activating the profiler the moment I’m noticing an issue or want to track something weird.
It’s the exact same way as you describe :
Profiling session starts great
Then after a couple of minutes it starts to lag a bit
Then if you keep going, FMOD itself is starting to drop some events, and the longer the profiling session, the more often it happens, to a point where you pretty much don’t have the same behavior as the “normal version”.
Notes :
this happens in both PIE (for UE) and Cooked/Standalone game situations.
tested with or without Cubase/UE5/SoundForce/SpectraLayers (and my tools for my everyday job) active in the background, same thing… it just happens sooner or later.
Same issue here, profile became unusable after 2/3 minutes (if lucky).Using 2.03.09 and this didn’t happened in the previous version we were using (2.02.19).
Also Live Update problem:
the first time you run the game goes to “syncing” and then on “sync on”
from the second time it get stuck to blinking “Syncing” (seems to work aswell but…)
muting or soloing events the first time take like 10-15 seconds.
Really love your product guys but this is becoming a real problem, quite unable to profile.
We’re about to mix a big game and we don’t know how we’ll do really.
Thank you all so much for sharing the detailed information!
The dev team has already started investigating this issue, and I’ll update this thread once we have more information to share.
In the meantime, some users have reported that adjusting the Live Update Preferences may help speed up the syncing process, which can be consider as a temporary workaround for now.
Thank you for sharing these additional details!
I have passed this Live Update issue along to the dev team for further investigation as well.
