Jittery Frame Rate with 120ms+ for PartilceSystem.GeometryJob execution
Since update 5.3, execution of the game has been incredibly jittery. Looking in the profiler, the process execution of "ParticleSystem.GeometryJob" is taking 120ms whenever the frame rate stalls, and a huge spike is recorded in the graph (see image below)
Is anyone else experiencing this? How might I correct this? This issue has only happened since the recent 5.3 release.

I was about to ask the same question!
After many tests, In my opinion, there is nothing to do, and this is certainly a know issue! I m just wondering why there isn't too much post addressing this problem, maybe this error rise in a very specific situation. Or maybe we are missing something after all!
The PS seems to be in focus right now (ref this post) the 5.3 Update was just the first step (first step often means some bugs!), the future updates will push the PS enhancement forward (and solve all what need to be solved! or hope so!) And the good news is that will give the "Next Gen" title to the PS, it will be able to do wonders while being more efficient! (once everything cleared)
This being said, it seems that the legacy particle system don't suffer from the issue mentioned above and can be used if an urgent fix is needed, though the best thing to do, in my opinion, is to wait for a fix!

Hey!
Looking at your screenshot, I think this is an issue we have fixed in the upcoming patch release.
But if it doesn't fix the issue, a bug report with a repro project would be really useful to us!
Thanks, Richard
Thanks for your answer! As soon as it comes out I test it and tell you

Hey @bhayward_incrowd @DrakharStudio - did you manage to sort anything out with this? I am seeing similar performance to you on an Android build though mine is continuous - not spikes! It went wrong when I updated from 5.3.1 to 5.3.4 and still broken on 5.3.4.p4.
same issue with 5.3.4f1 ...... Hi @richardkettlewell, any fix for this?
