1. The Hardware-accelerated GPU scheduling ("HAGS") feature in Windows 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
these instructions.
2. Your log does contain a streaming session 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 but OBS can help. Follow the troubleshooting steps at:
Dropped Frames and General Connection Issues.
18:38:41.569: User is ignoring service bitrate limits.
Start with that^
If still having issue, enable Dynamic Bitrate by going to Settings > Advanced > Network.
3. Your GPU is maxed out and OBS can't render and encode 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 V/G-sync or set a reasonable frame rate limit (144, 120, 60) that your GPU can handle without hitting 100% usage.
Enable "Use hardware decoding when available" in your Video Capture Devices (Cam Link 4K and Game Capture HD60 X)
In the encoder settings, set Multipass Mode to Single Pass and disable Psycho Visual Tuning. Those use additional GPU. Lower your Preset from P6.
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:

If still having issues, post new log.
