Lightmap performance drop

Hi,

I have a city model and 1 directional light.
When using realtime lighting i get 45fps (on android)
When using baked lights i get 30fps. I have 140 lightmap files (70 dir, 70 light) at 256 resolution.

So now i’m forced to using realtime.
Any way to resolve this?

Try using 1024x1024 lightmaps and less of them, maybe?

Having a lot of separate lightmap textures will increase the number of draw calls/reduce the effectiveness of static batching.

The original lightmaps unity bakes are 1024
I then changed their resolution to 256 after they were created.

My scene is a city with about 200 buildings + accessories…
