Description

Adding instanced static meshes in a random order by location gives 25% of normal frame rate, compared to adding them in order by X,Y,Z location.

Steps to Reproduce
  1. Download Sample: [Link Removed]
  2. Play in Editor: Standalone Mode
  3. Show FPS and Observe frame rate is very slow
  4. End Play
  5. In the "ism_spawner blueprint," reverse branch output in order to "build in order by X,Y,Z"
  6. Play in Editor Standalone Mode
  7. Show FPS and Observe:
    RESULT: frame rate is approx 2-3 times faster
    EXPECTED: frame rate to be approximately the same regardless of how static meshes are spawned into level
