Help Big (IMO) dip in fps

[josemendez]

I thought so as well, followed this instruction, and disabled vsync, but still the same result: FYI use unity 2019.4.22, Burst 1.4.8, Collections 0.9.0, Jobs 0.2.10, Mathematics 1.2.1... videoCard Geforce 1060 6GB, intel i7-8750H(pretty good for such scene)(and update info after disabling ThrottleStop 140 to 120...BUT the dip is still noticable)... What other options could be the problem?

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)
