In Unity2020.2.1f1 on a PC Standalone release build, this bug has eliminated the option to use of Unity Cloth on enemies for my project.

Given that my large seamless world streams in pooled enemies at runtime as the player moves around the world, I cannot use cloth as it stands due to this bug because of the framerate spike that occurs when I call GameObject.setActive(true) on a character that has a unity Cloth component implemented. I've managed to make every other aspects of this game stream content in and out seamlessly without frame rate spikes, except this one problem.

I would really appreciate if this were reprioritized to be fixed.

Yes please fix this!
We need to disable and enable cloth components for off-screen characters to save performance, but when we enable the cloth there is a huge spike which results in frame drops. There is no way to work around this currently :( I've tried to change enable from another thread, but it doesn't work - the main thread must be used, so it blocks everything else.

I'm sure Cloth has a lot of 'setup' to do when it is enabled, but it would be nice if there was some sort of option to skip some of this setup for just disabling and reenabling the cloth updates.

Either that, or also fixing the issue where off-screen cloth that is culled is still updated, would also help.

Thanks,
