Hi, everyone. Recently I found the performance of cloth physics drop dramatically since Unity 5.6 so I thought I'd share some info in case anyone else is affected. At first, I saw Alejandro0190's post which mentions his hair assets remove all the cloth physics because of the bad performance since Unity 5.6. I was very surprised and I did a quick test.The result is the same as Alejandro0190's. In my test scene, the performance in Unity 5.5 is about 3.6ms.The performance in Unity 5.6 and Unity 2017 is about 12ms. The CPU usage of Physics.UpdateCloth increase from 2.5ms to 11ms.Here are the screenshots. Unity 5.5.1f1 Unity 5.6.4p4 Unity 2017.2.0f3 I just put two skin mesh object into the scene(dress mesh is 9226 verts,hair mesh is 13906 verts), then add cloth component to the skin mesh object. Finally I paint the verts on the top of mesh to fix these meshes. Very simple. Tested with Unity 5.3.8f1, 5.5.1f1, 5.6.3f1, 5.6.4p4, 2017.1.1f1,2017.2.0f3. Tested with DX11 and V-Sync off.
