0. The version of Windows you are running has a limitation which causes performance issues in hardware accelerated applications (such as games) if multiple monitors with different refresh rates are present. Your system's monitors have 2 different refresh rates, so you are affected by this limitation.
To fix this issue, we recommend updating to the Windows 10 May 2020 Update. Follow
these instructions if you're not sure how to update.
00. 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.
1. Run OBS as Admin.
2. Recommended but not required: Having the YUV Color range set to "Full" will cause playback issues in certain browsers and on various video platforms. Shadows, highlights and color will look off. In OBS, go to "Settings -> Advanced" and set "YUV Color Range" back to "Partial".
3. 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.
