Do you also have performance issues with FPS? I used dynamic lighting 4.24 and was very surprised at how low the FPS was compared to the previous 4.21 engine. One project is assembled entirely on dynamic lighting. An open world of many objects, but I managed to achieve good performance on versions 4.21. In this version, I was using only one light source and I was horrified. Add a few more small lamps my FPS 18 frames. The scene is not big, it’s a house, but a lot of objects, but I used almost all the optimization tools. The result has not changed much.

Now there is no way out. I will dance with a tambourine near the PC. I’m just curious about the problems with light in 4.24. Will I alone experience performance loss.

I do see some noticeable FPS downgrade for dynamic lighting. I am a professor teaching architecture and I build some Unreal games for students to study architectural forms. My scenes are typically very simple but feature a dynamic directional light for simulating daylighting (like the one shown in this demo: https://www.youtube.com/watch?v=2t5BA6t0is8&t=62s). From 4.22 to 4.24. The average FPS of packaged games drops for about 2 to 5. For some students, that means their laptop with integrated GPU cannot handle the game very well.

I tested packaged games performance with MSI Afterburner. One interesting thing I found was that for 4.24 games, there was no FPS limit and your GPU load would soon go up to 99%. But 4.22 and older games would cap FPS at 60 FPS to lower GPU load. I am not sure if that has anything to do with the FPS downgrade in 4.24.
