System Information
Operating system: Darwin-19.0.0-x86_64-i386-64bit 64 Bits
Graphics card: AMD Radeon Pro 560X OpenGL Engine ATI Technologies Inc. 4.1 ATI-3.2.24

Blender Version
Broken: version: 2.82 (sub 6), branch: master, commit date: 2020-02-11 14:45, hash: c939b4df18
Worked: (optional)

Short description of error
I was wondering why my animation was so slow when adding a 4k vertice head to a 26k body.
I decided to tweak the mesh and delete all (already disabled) modifiers.
It goes back from 6fps to 24fps.

I don't know why since all modifier are deactivated. Can't pinpoint to which modifier exactly it is, but maybe it's related to the quantity I'm using.

It's because you're using shrinkwrap modifier along data transfer modifier in your low poly head object targetting another High poly version with 600.000 tris aproximatelly (that is also rigged to the armature. both are very cpu intensive)

I'd say it's not a bug. Cheers.

But you can see they are both disabled from the viewport. They shouldn’t be interfering with the performance.

The other head is disabled from the viewport and still linked the same way when the Frame rate is back to 24fps, so probably not related as well.

Even with the Original HQ Head (300k vertices) this occurs with disabled modifiers X deleted modifiers.

I'd say it's a bug. Cheers.
