Critical Two Instances
Two instances of OBS are running. If you are not intentionally running two instances, they will likely interfere with each other and consume excessive resources. Stop one of them. Check Task Manager for stray OBS processes if you can't find the other one.
Warning Old Version (26.1.1)
You are running an old version of OBS Studio (26.1.1). Please update to version 30.2.3 by going to Help -> Check for updates in OBS or by downloading the latest installer from the downloads page and running it.
Warning NVENC Start Failure
The NVENC Encoder failed to start due of a variety of possible reasons. Make sure that Windows Game Bar and Windows Game DVR are disabled and that your GPU drivers are up to date.

You can perform a clean driver installation for your GPU by following the instructions at Clean GPU driver installation.
If this doesn't solve the issue, then it's possible your graphics card doesn't support NVENC. You can change to a different Encoder in Settings > Output.
Warning Windows 10 1607 (EOL)
You are running Windows 10 1607, which has not been supported by Microsoft since April 2018. We recommend updating to the latest Windows release to ensure continued security, functionality, and compatibility.
Warning Non-Standard Aspect Ratio
Almost all modern streaming services and video platforms expect video in 16:9 aspect ratio. OBS is currently configured to record in an aspect ratio that differs from that. You (or your viewers) will see black bars during playback. Go to Settings -> Video and change your Canvas Resolution to one that is 16:9.
Warning Non-Standard Framerate
Framerates other than 30fps or 60fps may lead to playback issues like stuttering or screen tearing. Stick to either of these for better compatibility with video players. You can change your OBS frame rate in Settings -> Video.
Info Non-Default x264 Preset
A slower x264 preset than 'veryfast' is in use. It is recommended to leave this value on veryfast, as there are significant diminishing returns to setting it lower. It can also result in very poor gaming performance on the system if you're not using a 2 PC setup.
Info Windows Game Mode
In Windows 10 versions 1809 and newer, we recommend that "Game Mode" be enabled for maximum gaming performance. Game Mode can be enabled via the Windows 10 "Settings" app, under Gaming > Game Mode.
Info Dynamic Bitrate
Dynamic Bitrate is enabled. Instead of dropping frames when network issues are detected, OBS will automatically reduce the stream quality to compensate. The bitrate will adjust back to normal once the connection becomes stable. In some (very specific) situations, Dynamic Bitrate can get stuck at a low bitrate. If this happens frequently, it is recommended to turn off Dynamic Bitrate in Settings -> Advanced -> Network.
Info Network Optimizations
Network Optimizations are enabled. This option is disabled by default. It is only suggested to enable Network Optimizations if you are having issues streaming. The setting can be toggled in Settings -> Advanced -> Network.
Info Third-Party Plugins (1)
You have the following third-party plugins installed:
