I apologize. I think I made a mistake. I will update my post and clarify that I am using the newest available version of Sony Vegas Pro. Thank you.

According a hint by the team (thank you Neal) you can change which GPU will be designated as "Optimal"; but this must be done with a Windows setting, Windows does not allow applications to change this setting.

In Windows 10 and 11, the assignment is changed in the "Graphics settings" panel, accessed from "Display Settings". It looks like this in Windows 10:

After that change in Windows, your other GPU should showup as "optimal".

Be aware, that another reason could be that you use as preview quality "best/full". You could also try to decrease the preview quality.

Be also aware, that the i-GPU may not be as powerless as you think. Depending on your kind of footage, and especially for long-GOP footage, the i-GPU can support a nice playback. What are your settings in options/preferences/file I/O - here the default is the i-GPU on my system at "hardware decoder to use".

Wolfgang and Eric, I seriously appreciate your timely feedback. I will try this now and report back to you in just a moment. Thank you, again!

Wolfgang, I attached a screenshot of my File I/O settings, but I wanted to let you know that I did fiddle around with each setting over and over again, but the issue still happened. I set them back to default, because I don't want to accidentally ruin anything.

Also, I am attaching another screenshot of my graphics setting window, and I was hoping you could guide me with how to proceed from here, because your screenshot seemed far clearer than mine. I apologize for all the trouble.

Hi Yelandkeil,

I was so, so hoping your suggestion in the screenshot was going to help, but I tried it, and the problem is still happening. Nonetheless, thank you for reaching out, seriously!

 I will update my post and clarify that I am using the newest available version of Sony Vegas Pro. 

Please note that the newest available version of Sony Vegas Pro is still #13. That's not likely to change unless Sony buys the software back from the current owners (MAGIX Software GmbH since mid-2016).

Very good to know. This is totally irrelevant vkmast, but do you know when 3D tracking and planar tracking was introduced to Sony Vegas?

…….but do you know when 3D tracking and planar tracking was introduced to Sony Vegas?

@Benjamin-Davis - Why? What is it you’re trying to confirm?

Grazie,

Again, I don't want to derail too much from my original post, because this issue is driving me bonkers, but I was just curious when that feature was added. I was really impressed with some of the showcases of it in videos, and it was cool to see Vegas added that feature. Back when I first used Vegas years ago, I would need to manually keyframe everything and use the 3D tool to adjust all of the angles and perspectives. I have used Ae and Pr Pro for certain jobs, but aside from Photoshop, Adobe's user interface is just an intimidating mess that crashes too much.

Really, the only reason I ever liked Photoshop was because it helped with some user-interface design mockups for websites and software.

... do you know when 3D tracking and planar tracking was introduced to Sony Vegas?

Sony Vegas (i.e Vegas Pro 13 and earlier) never had 3D or planar tracking. The first version of Vegas Pro that introduced a basic form of motion tracking was Vegas Pro 16:

• Motion tracking enables the user to follow the motion of on-screen objects and apply video FX and filters to the moving area

Motion Tracking was further developed in Vegas Pro 17:

https://www.vegascreativesoftware.info/us/forum/release-vegas-pro-17-the-fastest-nle-for-passionate-creatives--116461/

• Motion tracking: Track motion in a scene and let other events or text follow the movement.

Later versions of Vegas Pro further developed tracking - but it's more 2D than 3D tracking. For true 3D tracking in Vegas Pro, you really need BorisFX's Mocha Pro OFX plugin or an older version of HitFilm Pro (one prior to the current release under ArtList's ownership) which has Mocha HitFilm. Older HitFilm Pro versions can usually be accessed on a video event on Vegas Pro's timeline.

Since VEGAS Creative Software (owned by Magix) now owns VEGAS, we just call it VEGAS now, not Sony VEGAS. Sony sold VEGAS to Magix/VEGAS Creative Software years ago.

Your jagged/screen tearing issue can be fixed by going into preview device preferences and enabling "wait for vertical sync". Then use the driver update utility in the help menu to download the latest studio driver for your 3090.

fr0sty and Dexcon,

I really appreciate you guys catching me up on all that has happened and what things have changed and when. It is incredibly helpful to know, and I already feel more comfortable reaching out here for questions. vmast also helped by linking me to a previous post describing the change. I definitely have some brushing up to do.

fr0sty, I saw a similar post earlier, but I will try doing what you suggested with the driver update utility. Thank you.

I am going to have to hit the hay tonight, because I have to be on set later. I will come back first thing and try everything and make sure to reach out to anyone and everyone if there is a solution. I want to thank you all again. I will be back here later on today (around 7 PM PST).

I know I keep saying it, but thank you all so much for the support. I am really looking forward to finally conquering this issue. I will be back soon!

For file io I would leave decoding to the more compatible Intel iGPU. You can experiment with turning on and off legacy HEVC if you use such footage. The legacy decoder is better for some media and worse for others.

Also, I am attaching another screenshot of my graphics setting window, and I was hoping you could guide me with how to proceed from here, because your screenshot seemed far clearer than mine. I apologize for all the trouble.

I think you have to enable the GPU accelerated hardware scheduling (you show in your snapshoot that it is off).

Then you should go to grafic settings (I work here with the German version, where it is "Graficeinstellungen"

Here you will have to search in the list for Vegas, and must include it.

If you have Vegas in your list, a double click opens the options. And here you can choose "high Performance"

Hope it helps. With my German system, I am not in the best position to navigate you to this settings.

On my German system, I make a click with the right mousetaste on the desktop. Here I choose "Anzeigeneinstellungen" - Display settings if that is the correct wording what I do not know:

And then hiere Grafic:

And inside Grafik, you have to search for Vegas. And then you can enable here the performance mode, as shown above.

@Benjamin-Davis as you probably have an alder lake cpu (iGPU 770), you would be better of upgrading your OS from Windows 10 to Windows 11. This may solve a lot of issues as the windows 11 OS is more up to date, and and has a thread director for better thread scheduling of a hybrid processor (E-cores+P-cores) like a Alder lake.

There is also resizable bar and above 4G decoding you can set in BIOS as you have a NVIDIA GeForce RTX 3090 which has 24GB of memory. With such amount of VRAM you should really "open the gates" as I would call it.

@Benjamin-Davis Your video card is obviously more powerful than your CPU, but for mere decoding preview, since your CPU and Video card are both hardware accelerated, the CPU wins as it does not have to delegate the decoding over the PCI bus to the card and receive the result back, and then send it back again to the video card to render the whole screen display including the UI.

as @RogerS mentions "For file io I would leave decoding to the more compatible Intel iGPU".

That is exactly what I do.

Hello everyone,

I am sorry for replying so late; I was not able to make it home until 1 AM (PST), and then I had to take a nap. I just woke up (It's 4:56 AM PST) and I am going to experiment with what RogerS, bitman, and Wolfgang replied. I will be back momentarily and respond.

The problem has been almost entirely fixed. There are some instances when playing back footage in the Preview Video window where there are some very minor "choppy" or "jagged" frames, but for the most part, it is completely fixed.

I am not sure who to click "Tag as solution" on, because it was a combination of peoples' suggestions. Is there a way to select multiple people for "Tag as a solution"?

Not really. Maybe it is a nice idea to describe the solution in a short sentence - and tag that as solution.
