The physics limit?

So I was almost finished with an amazing remake of the wasteland from jak 3, and then my physics bar it the max, completely shut down. Can someone PLEASE explain what it is and how I can fix it?

Not 100% sure what causes it, but i know large natural features have a huge impact. My BTB map Varsod 2 is almost entirely natural structures, and that maxed it out way before the object count. Try removing large rocks if possible as they account for 1% each.

Physics refers to objects interacting with one another, do you have a lot of loose objects colliding with each other?

Yeah, thx.

mine arent, no. Each phased cliff piece is 1% of the physics budget, and there are no large fixed or normal pieces in the map I maxed the budget for.
