Latest Nvidia Drivers 378.66 may break Preview Window in Vegas Pro!

Hi everyone.

This just happened to myself and 2 other people reported the same problem.

If you own an Nvidia Graphics card, do not update to Driver version 378.66 !
Installing this version will cause Preview Window in Vegas Pro to go black and no videos on timeline will show.

If this has happened to you, roll back to an older driver version.

Open Device Manager (right-click Windows Start in Windows 10) or select from Control Panel.
Open Display Adaptors, select your Graphics Card then right-click and select Properties.
Go to Driver tab and press Roll back, if it is available.
If it is greyed out, there is no previous driver version saved in your computer

If no previous version is there, you can do a manual search for your Graphics Card Driver and set the ALL.
This will show all driver versions every released - you can download and install an older version from here.

There are some reports that installing a CUDA Toolkit can solve the display problem with recent drivers: https://www.vegascreativesoftware.info/us/forum/anybody-running-nvidia-gtx5xx-with-cuda8--105524/

Otherwise, driver 372.90 sounds like a reasonable bet if you need to try an older driver.

Another report here, and the solution was to roll back to 376.33.

Does 378.66 only break preview completely or only when GPU acceleration of video processing is enabled?

I had the same problem with Vegas Movie Studio Platinum Suite 14 and driver 378.49 with a GTX560Ti. I had trouble searching the Nvidia site but found a 344.11 installer in my archives and am now running OK.

Only when GPU Acceleration is turned on in the Preference Settings.

Hi everyone too, for a positive note,

Just to report in my case, I do not have issues with 378.66, I suppose it all depends which is your PC's hardware & sw and type of nvidea card (Titan-x)

Those of us who were affected by this driver update, are all using older models of Nvidia like GTX 400 and GTX 500 series cards. As you have reported, more recent models are not affected in a negative way.

Just a big thanks to this forum community for indispensible help, especially with the brand new growing pains of Movie Studio 14!

Thank you for this thread! It just helped me solve another related issue which was that my preview window would not update while using any tool (eg. generated text, FX, track motion). As soon as I closed the tool it would update and I could view it. Turning off GPU support let me keep the latest video drivers, but fixed it so I can see a live preview while I edit things.

I lived without GPU support for years and I don't mind ignoring Sony's messed up feature until Magix gets around to fixing it.
