Hide Unity while using Syphon

[julienrobert]

Hi
I need to use Syphon to get the render of Unity inside MadMapper or Jitter. I noticed that the framerate of the runtime goes from more than 200 fps without using Syphon to 60 fps when I use it. I wonder if it is a limitation of Syphon or if I did something wrong.
Also, I guess the window of the runtime must take some performance if we can see it? I wonder if we could hide Unity completely to avoid taking performances…?

You can hide Unity yes, or not draw what you are rendering to the Syphon to the unity output. The less you draw the less you do.

As far as 200fps vs 60, I have no idea why it would do that, unless you’ve enabled Vertical Sync somewhere.

How do you do to not drawing what you ‘re sending to Unity?

Thanks

You can render offscreen to a frame buffer / texture and send that to Syphon. You don’t have to draw that output to the window. You can do everything ‘invisibly’ and it will save you some fill rate.

Just found that Draw scene tick box in the Syphon Server texture custom resolution script.

Thanks!
