Your log contains streaming sessions with dropped frames. This can only be caused by a failure in your internet connection or your networking hardware. It is not caused by OBS. Follow the troubleshooting steps at:
Dropped Frames and General Connection Issues.
You are running Windows 11 24H2, which will be supported by Microsoft until October 2026.
Your stream encoder is set to a video bitrate that is too low. This will lower picture quality especially in high motion scenes like fast paced games. Use the Auto-Config Wizard to adjust your settings to the optimum for your situation. It can be accessed from the Tools menu in OBS, and then just follow the on-screen directions.
