Using 14.3. Recently updated Nvidia Driver after a Windows reinstall, and now GPU Hardware Acceleration is causing a jumbled mess.  Clears up when I switch to Mercury engine software setting, but this takes about 15 times longer to export clips.  I downgraded to 14.2 just to see if that helped.  No go. I'm unable to downgrade the Nvidia driver for whatever reason. Thoughts?  Thank you

As Superdave notes, this is a bad driver from Nvidia. The latest Nvidia drivers are wonky across all video apps. Some can work with a 445.x driver, but many need to go back to a 442.x driver to get it working.

 

And as noted by Superdave, many (though not all) need to uninstall all Nvidia and do a clean install to get it working.

Hi Shattercone! Had the exact same problem. It's with the lastest nvidia studio driver (451.48). Had to clean install the previous driver (442.92) to get it working again.

 

Cheers, David
