Question. Did you guys happen to adjust some of your level streaming settings in this patch? In particular background streaming and the per frame time limits? Because 0.2.0.0 had way more stuttering than 0.2.0.1 (at least it feels that way).
These are the settings in your DefaultEngine.ini file that I’m talking about:
bUseBackgroundLevelStreaming=True
AsyncLoadingTimeLimit=5.000000
bAsyncLoadingUseFullTimeLimit=True
PriorityAsyncLoadingExtraTime=20.000000
LevelStreamingActorsUpdateTimeLimit=5.000000
LevelStreamingComponentsRegistrationGranularity=10
(although 20ms seems like a high value for PriorityAsyncLoadingExtraTime)
Also why did you disable the EventDrivenLoader? Are you affected by this? https://answers.unrealengine.com/questions/546689/event-driven-loader-issues-with-subobjects.html
And finally, I cannot fix the big stuttering that your LevelStream blueprint introduces by changing any of those values.
But my test blueprint (which is literally OnTriggerEnter -> StreamLevel) doesn’t cause the same amount of stuttering as seen when loading the Casino.
What’s your opinion on what might cause this? And is that even something you can fix without messing with UE’s source code.
