Question / Help 4k camera works lagfree on Linux, not on Windows


New Member
I tested the Logitech Brio recording in 4K without any perceptible lag on the Linux version of OBS, but on Windows I get a very obvious lag despite any configuration I try.

On Linux I configured the video format as NV12 on 4K, but on Windows this option does not exist for 4k video, despite being there for 1080p and working well on that resolution. Is this related to Microsoft DirectShow? Is there any alternative to make 4k capture on Windows work as smoothly as on Linux? Is it possible to force MMF somehow?
