I'm only vaguely familiar with Syphon, but from my minimal understanding, it's some sort of GPU-based frame sharing software?
Are you able to get your video input device to output to a Syphon server, and want to get the Syphon output from there?
What video device are you using that is so laggy with OBS? In what way is it laggy?
Thanks!Syphon looks like the stuff that would greatly compliment capturing. We'll probably implement support or integrate it somehow if we can.
