Size of a mesh vs performance

Hi everyone,

I’m trying to optimize every details of one of the mobile game I’m working on. I have a problem that I can’t really understand but may be I miss something.

I actually check the profiler of my game to see which mesh is actually taking the most of time to render. My surprise was to see that the “heavier” mesh was … the ground.

To be simple : We have a big 2tri plane mesh to make a “ground” in our game, with a colored material attached. This big 2tri plane is actually taking a lot of time into the profiler.

  1. Do you know why ?

  2. What I can do to optimize this ?

Thanks a lot :slight_smile:

Mobiles use tile rendering GPUs. Your 2-tri quad needs to be split up into every tile.
