I am facing performance problems in my project. It had stable 60fps the whole time. Now, after adding (and deleting) GUI for fluid renderer particle system testing, the fps drop to 25-30 when interacting with water. Disabling particles in the inspector fixes the fps but it wasn’t a problem up until I tried adding the GUI.
The amount of particles you set in the GUI is probably a bit too much for some systems. But even when removing the GUI component, the framerate is quite low with the default values (at least on my device)
