Kiyo Pro Ultra: 60fps, consistent frame skip pattern with 50hz and 60hz anti flicker. Never 60 unique frames per second!

Hi!
I do like the sensor and image quality but there are double frames (static frames) with a consistent pattern. Every x frames, it shows the previous frame instead of a new one, and then on the frame after that, the movement has jumped ahead, resulting in jerky video. If you’re a GSYNC gamer, you see and ‘feel’ this inconsistent pacing instantly. 

I have only found one setting to make a difference, and that is the 50hz or 60hz flicker filter. I’m recording either the Razer Synapse preview screen with OBS, or added the camera as a video capture in OBS, makes no difference, all at 60fps. 

Flicker filter:
50hz: Static frame every 4,4,4,8,4,4,4,8 frames 
60hz: Static frame every 24 frames

Nothing else makes a difference. USB ports, resolution, compression settings, camera settings don’t matter. CPU and GPU load is low. The camera is only shared by a keyboard on a USB 3.1 ‘hub’ (but directly plugged into PC) using USB Device Tree Viewer. Other USB ports don’t change anything. 

I know this is common for webcams when there is not enough light, but again that doesn’t matter here, I set the shutter to 1/60 or shorter and the image just gets darker with less light and brighter with more light, the double frame pattern stays the same.

I’m 90+% sure my camera is fine and my PC is fine. My old BRIO 4k almost never skips frames at 1080p60, it just doesn’t have the sensor quality.

Am I missing some magic setting? Or am I the first to critically analyze video for skipped / double frames? Surely not? I’m filming ‘’over the shoulder’’ videos in my race simulator rig as it is immersive to show my hands and the screens, so I really do need 60 unique frames per second. I feel there is some filter or something remaining somewhere that just stops unique frame output at a nearly 100% consistent frame pattern.

Any help appreciated, the camera is good otherwise but I need 60fps video, not a pause every x frames.
Regards,
Niels
