Hello all,
i am experiencing unexpected behaviours when it comes to performance issues and lighting.
I am working on an application which should run in standalone on the Meta Quest 3. This application involves a large environment with detailed models.
I am working with realtime lighting, as many objects will move in the scene. I’m using Unity 2023.2.20f1 and have only one directional light in the scene. However, this leads to performance issues when run in standalone on the Meta Quest 3.
I did some testing to figure out how i could improve this:
- Set all Mesh renderers in the Scene to Cast Shadows Off → no improvement regarding the Framerate. Why is there no improvement when no Shadows are casted?
- When i set Shadow Types = No Shadows on my directional Light, i’ve got a significantly higher Framerate. Shouldn’t this be the same as setting all Mesh renderers to Cast Shadows Off?
- Baked lighting improves the framerate, but as i already wrote, this is not really an option.
- Mixed lighting has not any performance benefits.
What would be an alternative to baked lighting? Why do i not get an performance improvement when switching all Cast Shadows to off?
Thanks in advance for any help!
