The log contains an Auto-Config Wizard run. Results of this analysis are therefore inaccurate. 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.

Your GPU is maxed out and OBS can't render scenes fast enough. Running a game without vertical sync or a frame rate limiter will frequently cause performance issues with OBS because your GPU will be maxed out. OBS requires a little GPU to render your scene.

Enable Vsync or set a reasonable frame rate limit that your GPU can handle without hitting 100% usage.

If that's not enough you may also need to turn down some of the video quality options in the game. If you are experiencing issues in general while using OBS, your GPU may be overloaded for the settings you are trying to use.

Please check our guide for ideas why this may be happening, and steps you can take to correct it: GPU Overload Issues.

The encoder is skipping frames because of GPU overload. Read about troubleshooting tips in our GPU Overload Guide.

The Hardware-accelerated GPU scheduling ("HAGS") feature added with Windows 10 is currently known to cause performance and capture issues with OBS, games and overlay tools. It's an experimental feature and we recommend disabling it via this screen or these instructions.
