Performance rendering Sweep and Limit Sop

Beginners
1

Hello,
I’m trying to make a data vizualization of a movement, like a golf or tennis swing.
Here is my first test with a lot of sweep and Limit Sop and a few Particles.

My frame rate is 15fps which is not very good… :frowning:
When i look at my performance window, some operations take 4ms (rendering window)…
I have a Nvidia GTX 780

Any idea how to optimize the render time? :question:
Thanks!
Baptiste

Rendering a window is the time is takes to Render, not much you can do directly there. Also if vsync is on this number will report the time the GPU is waiting until the next frame can start, so it is often misleading. (for example, if your frame calculations only take 2ms, rendering a window will report 14ms because each frame takes a total of 16ms at 60fps everytime. Turning off vertical sync you can see this change)

Most likely the animating of SOPs is slowing you down.

  • Try reducing number of points in SOPs
  • Try using Primitive Type SOPs where you can, much faster but not all SOP filters will work with them
  • Try using GPU instancing for your geometry (See Geometry COMP) instead Copy SOPs and Limit SOPs?
  • Are you running in Perform Mode?

Without seeing your network, hard to recommend optimizations.

Thanks Ben,

I disabled th VSync but it did not change a lot.
I’m going to try the differents things you told me (instancing,…)
Here is my .toe, maybee you’ll see a big beginner mistake! :blush:

Cheers,
