Help Big (IMO) dip in fps

[alex798]

I understand you're getting 90 fps on an empty scene (no obisolver) with vsync disabled?

That particular scene's solver takes around 0.7-0.9 ms/frame to update.

90 to 70 fps = aprox 3 ms/frame. That's around 3 times slower than it should be.
What are your project's timestep settings? (fixed timestep, max fixed timestep, both found in Unity's Time manager)

Fixed = 0.02, MaxAllowed = 0.33, Scale = 1, MaxParticle = 0.03
