The "Latest GPU Driver" Farce

john_dennis wrote on 3/9/2018, 10:17 AM

After this debacle, I kept the same video driver (64 bit driver (version 9.17.10.2792)) for most of the four-year life of my i7-3770(k) machine as an editing computer. Now, the machine serves as a Home Theater PC and a test machine, so I'm free to do silly things like update video drivers whenever I'm bored.

Newer is not always better. Not to worry. I have a system image.

Disabling GPU acceleration fixed the preview problem in Vegas Pro 13. This is generated media, folks.

Intel released this in the last two months:

This looks almost like the old and still existing AMD bug whereby cropping a video's width on top of another video below will result in "flashes" similar to what the generated text does in your video. The only work around is to increase the height of the cropped video by the smallest amount. For example: 1080.00 would be 1080.01. I think I even a post about that here in the forum, just cat find it.

Edit: here is the link to that thread.

Thanks. I'm not going to "fix" it, though I may study it some more. The Project Properties were 1280 x 720.

It would be nice to know if the problem is similar to what I experienced with VP13 build 453. It might be still in VP15?

You're welcome to try the project. I'll report findings based on other Vegas versions and hardware, later.

@ OldSmoke

Results From All My Machines:

Intel Q9450 - nVidia GTS450

Vegas Pro 12-770 Ran With NO Errors with GPU On or Off.

Vegas Pro 13-453 failed with GPU ON.

Intel i7-6850K with AMD RX480

Vegas Pro 13-453 failed with GPU ON.

Vegas Pro 14-270 ran fine with GPU ON at the full 60 FPS frame rate. That's Good!

It appears that I might have stumbled on to the bug that you mentioned while changing video drivers.

@john_dennis Thanks for testing! I am not at my machine but I believe that changing the height in all track motion from 720.00 to 720.01 will get rid of the bug even with GPU on.

I verified your solution on my oldest machine. I only had to change the vertical dimension of the Pan/Crop for the Generated Media that was less than full screen. I wasn't able to get +/- 0.01 to work, but +/- 0.1 worked fine.

Since the bug didn't appear in my Vegas 14 installation, I'm assuming it was fixed and not re-introduced in 15.

Yes, that doesn't work, it jumps back to .00. Thanks again for testing it.
