Framerate drops when a mesh is further away

Hi!

I am developing a game for the vr headset Pico G2 (similar to the original Quest) and have run into a rather weird issue.

If I have a mesh approximately 1500 units away from the camera, the performance is fine and the game hits 72 fps. If I move it further away to say 4000, the performance drops to about 60.

This happens with both a standard cube and with more complex meshes (up to about 60 000 verticies). The material on both objects is a basic unlit material without any transparency.

Anyone have any idea of what is going on?

This works fine:

Layer 1
Layer 11893×986 110 KB

When doing this the framerate drop occurs:

Layer 2
Layer 21473×986 36 KB

I am not animating them in any way, this is based on moving in the editor and building.

Thanks in advance :slight_smile:

Have you already solved it? I also want to know the reason
