System: Mac Studio M4 Max 36GB — macOS Tahoe 26 — LG HDR 4K external display @ 3008x1692

OBS last version

Problem:
Recording is stuttering/laggy regardless of settings. Tried both Display Capture and Window Capture with macOS Screen Capture source. Encoder set to Apple VT H264 Hardware, output 1920x1080 @ 60fps. Base canvas 6016x3384 (Studio Display native). Frame drops and stuttering persist.


Note: QuickTime Player records the screen smoothly on the same machine with no issues, suggesting the problem is OBS + ScreenCaptureKit on Tahoe.


thanks in advance
