Other may ask for logs, but I'm a newbie and wouldn't know how to read the logs. So my feedback will be based on basic troubleshooting (unrelated to OBS)
- Have you started Task Manager and do you monitor Performance. Have you research what is on that screen, what is means/how to interpret?
- Have you turned off unnecessary background tasks
- Starting a stream and recording is a lot of work for your computer, and it is easy to create bottlenecks. For example, inadequate RAM, a slow SSD, or worse a HDD. etc
- Do you start the strea/recording, shortly after booting the computer and/or logging in (ie not letting the computer complete initial tasks and settle down)?
