FS_Master field custom triggering cause huge rendering lag

If I’m using FS_Master field with a delay trigger everything is OK and smooth. I can have multiple fields in the scene and rendering is over 60 FPS. But when I switch it to manual triggering, it started lagging.

The game thread just waiting on some tasks…

There are a lot of background threads that do the same


But most of the time it is just waiting, there is some Chaos stuff, but just a fraction of the whole time.

I found, that it is caused by “Initialize Field Variables” inside of FS_MasterField. Which already happens also on Event Beginplay. Why it is there again? It is a bug or purpose?

I’m expecting that it is important to call it when I will do some runtime configuration changes of the field?

Or is it already a bug that it takes so long time?

Interestingly physics simulation did not start after this lag, but already during it. So physics simulation start immediately, but it lags so much, that the whole simulation is done before it restores the original FPS. I see just 3 frames of the whole simulation.

When I skip “Initialize Field Variables” everything is smooth again.
