2D Water simulation is extremely heavy

Hi,

I saw the following tutorial and wanted to give it a try

In summary you use many sprites with round colliders to simulate water particles. However it seems very impractical and heavy to use. Is there any way I can optimize this fluid “simulation”?

Here’s an image of the prefab of the particles:

When I exceed the 3k vertex the fps drop to 1 :disappointed:.

Thanks in advance! :grin:
