1. To ensure that OBS Studio has the hardware resources it needs for realtime streaming and recording, we recommend disabling the "Game DVR Background Recording" feature via
these instructions.
2. Run OBS as Admin
3. Multiple Game Capture sources are usually not needed, and can sometimes interfere with each other. You can use the same Game Capture for all your games! If you change games often, try out the hotkey mode, which lets you press a key to select your active game. If you play games in fullscreen, use 'Capture any fullscreen application' mode.
4. Your log contains no recording or streaming session. Results of this log analysis are limited. Please post a link to a clean log file.
To make a clean log file, please follow these steps:
1) Restart OBS.
2) Start your stream/recording for about 30 seconds. Make sure you replicate any issues as best you can, which means having any games/apps open and captured, etc.
3) Stop your stream/recording.
4) Select Help > Log Files > Upload Current Log File. Send that link via this troubleshooting tool or whichever support chat you are using.
