without telling what encoder you are use its hard to say ^^ logs are really helpfull
but default an overload is a overload so reduce the load
means look that your CPU and GPU far away from 100%
but without a log we can't help
someone told me it is because my files are getting saved on another hardrive from where obs is installed, but i don't know how true this is, but here is a log file from today, i just turned on my recording to see if auto config would help but it didn't so stopped the recording again as it becomes a huge stutter:
