Stutter when using Niagara FX for the first time on Quest 2

Hi Guys,

We develop a shooter on Quest 2 with UE 4.27.
Every time we first launch the game and we fire, we spawn a FX made with Niagara and there is stutter the first time the FX is spawned. We have a stutter for every unique FX we spawn (one for hit, destruction…).

I thought it was coming from the texture and tried disabling the texture streaming on each textures. This didn’t helped.

Does anyone have a suggestion about what I could try ?

      PSO Caching | Unreal Engine Documentation

       

      I haven't done this myself yet, as it seems to be a process that would have to be repeated for each package, and I haven't shipped anything yet.  For my project, during the initial load when I have everything faded to black, I have a warm up phase that spaces all the Niagara FX directly a meter in front of the camera.

      If people came across this message. The only current solution is to implement PSO caching so that shaders are precompiled.
