I'd like to ask this- in your sample Rocker scene in editor(all burst steps made) on my system fps with and without solver jumps from 96 to 76- for 1 meter rope with 12 particles it's too big (imo)- it is standart or some issue?

(20-06-2021, 03:33 PM)josemendez Wrote: This doesn’t sound normal. That scene runs at 200 fps on a 9 year old 2 core cpu, around 580 fps in a newer 4 core cpu. If using Burst, make sure that the jobs debugger is disabled (as well as all other performance-hungry burst/jobs settings). See:
http://obi.virtualmethodstudio.com/manual/6.2/backends.html

Also remember to disable vsync if you want to profile actual ms/frame, instead of capping fps to your screens refresh rate.

What other options could be the problem?

(20-06-2021, 04:35 PM)josemendez Wrote: 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)

(20-06-2021, 04:39 PM)alex798 Wrote: Fixed = 0.02, MaxAllowed = 0.33, Scale = 1, MaxParticle = 0.03

Can you take a pic of the profiler in timeline mode and share it?

Also, can you answer whether this is correct?:

(20-06-2021, 04:52 PM)alex798 Wrote: About fps on empty(without anything) it is about 100-110 with cpu frame locked on 2GHz, and 150 with turbo(4GHz)(FYI it is laptop)- maybe Quality = ultra do smth with fps?

Quote:(with profiler get 160-200 without turbo, and 220-300 with)

(20-06-2021, 04:59 PM)josemendez Wrote: Doesn't make any sense...    with no vertical sync, you should be getting at least 1000 fps. There's barely anything for the engine to spend time on.

I'm testing on a 9 year old mac book air laptop, which has much worse hardware than yours, and I get 2500-3000 fps:


Can you share a screenshot of your profiler? That way we can tell what's so much time being spent on.

While profiling you should get less fps, not more. Something doesn't add up here :/.

Those are turbo with profiler stats:
