Question

Lower frame rate in Unity app

Hello!

I am currently doing a project where I need to reduce the frame rate in passthrough significantly (5-30fps). I cannot find anything in the PassthroughCameraApiSamples or in Meta documentation and have tried throttling to "fake" fps drops in multiple ways.

Does anyone have a working solution on how to lower passthrough fps?

Thanks in advance!

Unity and Meta’s Passthrough API don’t provide a direct way to lower the camera FPS. A reliable workaround is to render the passthrough texture to a RenderTexture at a lower update rate—use a coroutine or timer to update the texture only at your target fps (5–30). This effectively throttles the visual framerate without affecting the underlying camera feed.

    Thank you for your answer! However, I was not clear in my previous post - I want to reduce the update rate for 3D passthrough. Will your solution still work for that?
