The new Windows 10 Hardware-accelerated GPU scheduling ("HAGS") added with version 2004 is currently known to cause performance and capture issues with OBS, games and overlay tools. It's a new and experimental feature and we recommend disabling it via this screen

You are running an old version of OBS Studio (27.2.3). Please update to version 28.0.2 by going to Help -> Check for updates in OBS or by downloading the latest installer from the downloads page
and running it.
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.
Recording at a tremendously high framerate will not give you higher quality recordings. Usually quite the opposite. Most computers cannot handle encoding at high framerates. You can change your OBS frame rate in Settings -> Video.
You are running Windows 10 21H2, which will be supported by Microsoft until June 2023.
