Unreal Engine, Spout and Framerate

Unreal Engine

A summary of several conversations across different mediums

Hi,

I noticed that the framerate in Lightact drops when I send a texture to it via Spout from Unreal Engine.

Any ideas?

Thanks!

Hi,

That usually happens for 2 reasons:

  • if you play UE in Editor than the moment UE Editor loses focus, the framerate drops. You can notice that even when Lightact is not running.
  • if you run a standalone or packaged game, Lightact can drop framerate when UE has focus. This happens because UE increases the resource cost the moment it gains focus. If another program has focus, even if it’s not Lightact, Lightact’s framerate should increase to normal.

If you want to mitigate the second issue the possible steps in Unreal Engine is to set a fixed framerate.

Thanks!
