SplitCam source stuck to 29 FPS


I'm using a 1080p60 webcam on SplitCam v. 10.5.12 x64
My scene is configured to [email protected] FPS
The preview in SplitCam window is smooth and actual 60 FPS

But whenever I try to use my SplitCam source in another software such as OBS, Discord or Nvdia Broadcast, it shows as [email protected] FPS, regardless of the FPS settings in the source.

Did I miss something ?

Problem still occurs with the latest version (v. 15.5.28 x64)

Is there a way to remove this 29 FPS cap ? Maybe did I miss something ?
I bought a 60 FPS webcam and not being able to use it at its full potential with SplitCam is very frustrating.

It's should work. Let,s investigate the issue. How do you check fps on obs and other soft? please, describe your pc, what CPU, video...

What I'm trying to achieve is to fork my Logitech StreamCam so I can use it both in OBS and in Nvidia Broadcast (so I can have a scene with the background removed by Nvidia Broacast and another one with the background using SplitCam Video Driver as source)

Nvidia Broadcast indicates 1920 x 1080 @ 29 FPS for SplitCam Video Driver. I can choose other resolutions but all of them are capped to 29 FPS (see attached screenshot)

In OBS, it says "Framerate identical to the output (automatic selection: 29.97 NTSC)" (see attached screenshot)

So it seems that it tries to match the NTSC framerate instead of using 60 FPS (or 59.94 FPS)

Here is a video capture of all the 3 softwares filming a 60 Hz flicker video :
The SplitCam preview window is smooth unlike OBS and Nvida Broadcast

Nvidia Broadcast and OBS operate properly at 60 FPS when the Logitech StreamCam is selected.

I run Windows 10 on an AMD 5950x PC with an RTX 3080 and 32 G of RAM. Check attached CPU-Z report for details.

Thank you. We found the issue. On next release it will work better, but still cannot achieve 60fps on driver output (selection will be posible ). Working on it.
