Low FPS in Play Mode and Standalone, but in Editor everything is fine.

Hello,

FPS in an almost empty location drops from 60-70 to ~ 30-37 in “Play”,
if I’m in “Standalone” then it drops to ~ 33-39.

My computer:
GTX1060 (6GB); i5-6600; 16RAM

  1. At the level there are no more than 200 meshes that have from 12 to 300 triangles. Only 1 has 6500
  2. Created an empty character, did not help.
  3. I don’t use event ticks
  4. Smooth Frame Rate - unchecked
  5. MaxFps - 144
  6. “DefferedShadingSceneRenderer Render Finish” - has a delay of 10-12ms, Frame - 30ms, Game - 10-12ms, Draw - 0.13-0.15ms and GPU-24-30ms.
  7. Clicked on the “Build” button. Everything was done successfully, but the FPS does not raise.
  8. Packaging the game doesn’t help.
  9. Removed PostProcess and ExpotentialFog to see if there was a difference. No difference.

What frame rate do you get in the default example level?

My first guess would be that you’re doing heavy pixel shader work and PIE is running at a lower resolution, and when you go to run in Standalone it is probably fullscreen so your performance tanks.

If that’s the case, my followup assumption would be that your scene has a lot of lit translucency.

Thanks for the answer,
The problem has been resolved.

Thanks for the answer,
The problem has been resolved. A couple of months ago I changed the navmesh settings, and changed it so that from 90 fps it became 60 and I somehow missed it, and then the fps became 30 :slight_smile:
