We have heard the feedback around users wanting to hide the mouse cursor in video recordings. Today there is no official support for hiding the mouse cursor; however, we do have a workaround via a regkey that may work for you until official support is in place.
To hide your mouse cursor while recording using GeForce Experience, download and run the following reg file: ShadowPlayCursorCaptureDisable.reg
Please note, once you download and run the Disable Reg file to hide your mouse cursor in your recordings, you must reboot your system.
If you would like to show your mouse cursor in your recordings again, you must download and run the following reg file: ShadowPlayCursorCaptureEnable.reg
Please note, once you download and run the Enable Reg file to bring back your mouse cursor to your recordings, you must reboot your system.
We hope to provide a proper implementation in an upcoming GFE release.
