Vegas 20 wt Nvidia Drivers: Preview Freezes Video with FX panel open

MMiles wrote on 7/27/2023, 5:07 PM

Computer: Lenovo Legion 7i Laptop, on-board Intel UHD Graphics and Nvidia RTX3070 both with latest drivers

OS: Windows 10 x84 (10.0.19045 Build 19045)

Application: Vegas Video Edit 20 (Build 411)

Nvidia GPU: RTX3070 with 536.67 Studio Driver (latest)

 

Problem: Opening the FX Plug-In panel and selecting a plug-in will cause the video preview to freeze (audio is okay). Upon closing the FX Plug-in panel the video will resume.

 

In searching the Vegas forums I've found a couple of solutions that are mainly:

1. Revert the Nvidia driver to version 522.30

2. Change the Nvidia GPU 3D Settings using the Nvidia control panel to: OpenGL GDI compatibility to "Prefer Compatible"

Comment: By reverting the Nvidia driver you lose all the benefits of the latest driver, including stability. For #2, I'm not sure about what that might do to performance ??

 

3. Vegas Support suggested a third option (in fact it's the only one they came up with). That is to disable the GPU Acceleration in Vegas (Options/Preferences/Video Tab) GPU Acceleration of Video Processing set to "Off".

Comment: While I'm not sure how this would affect Vegas rendering, some plug-ins that are more GPU intensive (such as NeatVideo 5.5.10) will take a big hit in performance.

 

In summary, I've tried all three and they seem to basically work. But I haven't done any hard tests mainly because I'm tried of fiddling around and plenty irritated that this issue even exists as I'm trying to be a good Magix/Vegas customer. Note: NeatVideo seems to think this is a Vegas coding issue and not the Nvidia drivers.

The question I have at this point is: Which method of the three above is the best way to go in your opinion?

Thanks,

Mike

This has been a problem with Nvidia's drivers for some time, and they even acknowledged it was a problem, then released a new driver claiming they'd fixed the problem, but it persisted anyway, and now Nvidia is ignoring anyone who brings it up.

I recommend and use 2 myself and encourage you to file a support ticket with NVIDIA so they know this is still a problem. I did.

(3 will kill performance so I can't see why they'd recommend that.)

Thanks Fr0sty. Roger, I did file support tickets with all three. We shall see.

Sounds good. I'll follow up on my ticket, too, with NVIDIA and see if we can get their attention.
