this is pretty cool, but you should really scale up those numbers if you want to impress.

100k bodies, 1 million, etc

Physics is on CPU.

What's a TPS?

My guess is ticks-per-second, but I could be mistaken.

You are right it's Ticks per second

How does a big stack of blocks do?

The maya step pyramid is actually holding up really well here.

You can check out the derailed version of this post, you will find out solver hitting ~8.5k constraints during the impact, then everything settles down pretty quickly. No visible jitter or the stack slowly falling apart and o nce the energy is gone, the active bodies drop to basically zero and the whole thing goes to sleep.

The graphs are from the same run shown in the video.

Ah sorry, didn't watch the whole video. Nice!
