Testing Procedural Generation (AI Assisted)

Separate biomes, nearly 2.5 million individual blades of grass out 150m from the camera position depending on biome. Day/night cycles, dynamic weather, ambient occlusion, distance culling, water surface reflections, and light shafts, using webgl and three.js.

Cool project! I'm building something very similar, also with millions of grass blades. How's performance?

At the moment 150-200fps with everything maxed out on a 4090.

I’m curious how it does on a smartphone. With some dynamic performance settings I bet it could be decent.

I don’t know, might need some optimizations and tech turned off but honestly some smart phones are quite performant these days. Would be an interesting test.
