Short description of error
Collision on Properties is very badly LAG

Exact steps for others to reproduce the error
MacOS 13.5
Blender 3.0.1, 3.4.1, 3.5.1, 3.6, 4.0 very badly lag during play on Cloth and Collision button.
My file is Lola Bunny 4.0.blend that version.
I did save previous from 4.0 to 3.6 then to 3.5.1 then to 3.4.1 document .blend

Explain:
there Timeline and push the right key from 1 to 2 timeline cause wait for a while then finish and try push the right key from 2 to 3 timeline cause wait too lag.

for Mac Push the Shift + Spacebar key (start play) cause wait too long super lag.

Hi @Kent-Davis , can confirm it's laggy, but if I'm understanding correctly, the old cloth/physics system are likely gonna be removed and currently there's no people to maintain that part.
