Global Illumination - good FPS in Editor, terrible in Build

Questions & Answers

As the title says. I’ve got to make a scene for tomorrow and I’m getting terrible FPS on baked Global Illumination in the Build - while in editor everything runs fine.

Editor - 60 FPS
Build - 20 FPS.

Scene is made with simple ProBuilder geometry, one big room.

WTF?

Maybe your Editor has a lower resolution than your built version.
