Hi,

capturing 4K 30fps with the Elgato 4K Pro Capture Card on the new OBS 21 version results in ~24% lagged frames due to rendering lags/stalls. I am pretty sure that this is connected to OBS 21 as I never had the issue before with hours of captured gameplay on the same setup. Capturing via the Elgato 4k Capture tool works fine without issues.

I rolled back to version 20.1.3 and the issue was gone. I captured the same scene on 20.1.3 0 lagged frames, on 21.0.1 its 24% - both log files are attached, its a short clip but longer recordings had the same result. I had a longer recording (1 hour) with the same result but the log file is gone.

Best


Michael
