12:31:35.890: Warning: OBS is already running!
12:31:35.890: ================================
You've got two copies of OBS running at once, which can negatively impact performance.
12:31:35.892: Windows Version: 10.0 Build 17134 (revision: 523; 64-bit)
12:31:35.892: Running as administrator: false
12:31:35.892: Aero is Enabled (Aero is always on for windows 8 and above)
12:31:35.892: Windows 10 Gaming Features:
12:31:35.892: Game DVR: On
Windows is out of date and Game Mode is on by default and cannot be switched off. Read the instructions in the signature below to find out how to update Windows to turn this feature off. This feature negatively impacts OBS performance.
This is distinct from Game DVR and/or Game Bar, but those should probably also be turned off.
12:55:58.571: Output 'adv_file_output': Number of lagged frames due to rendering lag/stalls: 2495 (4.1%)
12:55:58.572: ==== Recording Stop ================================================
12:55:58.573: Video stopped, number of skipped frames due to encoding lag: 24405/61474 (39.7%)
You are overloading your GPU, both in terms of rendering frames and encoding them:
12:31:37.268: - source: 'Display Capture' (monitor_capture)
Display capture is less performant than game capture.
12:31:36.655: YUV mode: 709/Full
This color setting will not look correct in some browsers.
Single machine setups for 1080p60 can be challenging. You may wish to switch to either 720p60 or 1080p30, or adjust settings in your game (such as capping framerate) in order to keep GPU load around 90% or less to allow for OBS to have the GPU access it needs to run.
Alternatively you may wish to run the Auto-Configuration Wizard from the Tools menu, which will ask you about your usage and suggest some basic settings.
