Runtime PCG spiking

Hey everyone, I am noticing that my PCG (Generate at Runtime, Partitioned & Hierachical Generation) is creating spikes from time to time when I move around [img 1]. Most of the time the UPCGSubsystem is ~70 μs, just sometimes it suddenly spikes with ~4ms. Has somebody ideas why that happens or how to optimize this? Some additional information of my setup: My graph is fairly simple.

  • I samples points once (using the voxel plugin, but the idea how it samples is the same). [img 2]
  • I feeds those points into a loop subgraph (loops through an array of dataassets) that I use as a biome filter (it uses feedback points to progressivly filter the points). [img 3]
