For the correct functioning of MB STUDIO with your NVIDIA graphics card it is necessary to install this driver https://us.download.nvidia.com/Windows/551.86/551.86-desktop-win10-win11-64bit-international-nsd-dch-whql.exe

This driver must be used exactly, neither an older nor a newer version. Also windows update periodically replaces the nvidia driver with another version that blocks the video encoders from working and when this happens you need to reinstall this driver.

Also during installation be careful to choose "graphics driver only" (Do not install GeForce Experience at all!)

Windows may periodically and automatically update the NVIDIA driver to a newer version, however the latest NVIDIA drivers are currently problematic and cause problems with MB STUDIO. I therefore recommend disabling hardware driver updates on your computer:

1) download this file: https://www.mbradio.it/download/disable_driver.zip

2) unzip the .zip file and double-click on the disable_driver.reg file and confirm adding the command to the registry

Please note that this setting only blocks hardware card driver updates, it does not block normal Windows software updates.
