Had similar problem with GTX1060ti.  Used an older driver and all was well.

Sound advice from j-v.

Thank you for the answers. Unfortunately, the driver installation package I got from Nvidia for drivers 391.01 indicated that "no compatible graphics hardware" was found and I could not proceed with the installation. I'm not familiar enough with driver installation to get past this, so that path may be a dead-end for me. As for upgrading VPro: that's certainly an option, but I just started using VPro 14 and I'd like to learn more about it before buying another version.

What is curious to me is that my card was initially shown as an option, and it wasn't until I selected something else that it disappeared. Does anyone have any ideas about that?

Upgrade your NVidia Drivers. Just yesterday they released new drivers. And they released specialized creative drivers and gamer drivers, take the creative drivers. They improved A LOT in speed, your GTX1660Ti should be superb now.

Thank you. I will try the creative drivers, but I am not hopeful they will work since the problem is not so much my performance, but rather that Vegas Pro 14 doesn't seem to even recognize that I have a GPU in the first place.

On my laptop, with Nvidia Geforce GTX 1050 and those creative GPU drivers 419.37, in the Vegas 14 latest build Options/Preferences/Video no GPU available and no MC renderoptions for that GPU.

Thanks @j-v. I believe you've saved me the time and effort of trying this myself.

That is super strange. Well sorry that it does not help at all.

Could this be the old GPU Preview/Render issue of Vegas? I dont remember about VP14 everything.

But try to search for it, if it changes anything:
Press and hold CTRL+Shift go to Options>Preferences> and now it should enable the Tab 'Intern'. Look into it if there is any Option about "GPU", just search for GPU and maybe if you set it from FALSE to TRUE restart Vegas if it helps?

Just a suggestion. I remember at least in VP11-13 this was quiet common of a problem.

@eikira
You meant this

My suggestion is that modern cards with the newest driverversions are not recognised by that older program and I have no intention to try it by installing one of my still olders Sony Vegas versions 8-13, although I tried it earlier and all installed well under Windows 10 but I expect to see the same.
As I well rember with my very old memory (😉) those Options to show the GPU-use were in those programs not available.

depends on how old of a program you are talking about. About 7 years ago i did a test with GPU encoding on my old Sony Vegas 11, and depending on the drivers, i needed to activate it manually in exact the options you screenshoted.

@eikira

But you're talking here about a total different function of a GPU.
The OP is asking about "preferences->GPU acceleration of video processing" and that has nothing to do with the GPU rendering that was available in the older versions as CUDA in the MC and Sony AVC codecs.
In the newest version that render option is not available anymore in the default settings because it was an old and not longer supported renderhelp.

@j-v well, it was talked about rendering to. but i see what you mean. still its not disconnected entirely. both is gpu accalareted in the end.

but i just installed again VP14 and see if i can reproduce that issue. and i CAN.

1. Open VP14 Options>Preferences> GPU Acceleration> from GTX960M to OFF. Close VP14
2. Open VP14 Options>Preferences> GPU Accleration> GTX960M disappeared.
3. Close VP14
4. Hold and Press CTRL+Shift. You will be asked if you want to reset VP14. Press Yes.
5. Open VP14 Options>Preferences> GPU Accleration GTX960M is again avaible for selection.

If you have many UI and Interface set up to your likings, you will lose everything of course, you have to manage all the Windows to your preferences, BUT this is the solution so far, that you can see AND select your GPU again where befor VP14 clearly deleted the GPU entirely from the list.

@eikira

@j-v well, it was talked about rendering to. but i see what you mean. still its not disconnected entirely. both is gpu accalareted in the end.

The question in the OP was
"Can someone help me figure out why my card is no longer an option under GPU acceleration and how I can get it back?"

And in my first post I gave him a solution at .2:
"2. Install driverversion 391.01 for your new Nvidia card."

Your solution in your last post is

1. Hold and Press CTRL+Shift. You will be asked if you want to reset VP14. Press Yes.
2. Open VP14 Options>Preferences> GPU Accleration GTX960M is again avaible for selection.

I'm curious if that is also with the new creative drivers you suggested to use.
Please give here a screenshot of your version nummer included with your used driverversion for that GTX 960M and the Option/Pref/Video settings for that GPU ass I give here without that last possible option

If your given option with a also good card for newer versions is a fact then for users of older and higher versions of Vegas it has no gain to spend extra money for a newer GPU.

In the end i dont think anymore at all that this is a driver issue at all. I accuse magix for making it unneseccary hard for the costumers. I will explaine shortly why.

I'm curious if that is also with the new creative drivers you suggested to use.

Most likely it will be the same case and result.

Will not help, right now i tested this on my Notebook and that uses Win7 still. I just wanted to see if there is something up with VP14.

Probably will not help at all. Now to my accusations.

To me it looks like magix forces costumers to buy new versions. Because after i managed to bring back the selection of the GPU in the Preview acceleration options, after i closed it and reopened VP14 its gone already AGAIN. And with a reset you AGAIN can bring it up to show and select. Since Vegas checks for updates it probably writes in some settings to disable the GPU.

Now i will try to test if it with internet connection disabled completely to see if there is something to my accusation.

Thank you both, @j-v and @eikira! Before I file a ticket, I'd like to understand something better. @j-v said in a previous post:

It seems there is a distinction between "video processing" and "rendering", that I was not aware of. Interestingly, a help document I found on the Vegas site says something similar. Can you help me understand what the difference is and in what context each of them is used? For what it's worth, what (I think) I'm interested in is rendering: I want to use the capabilities of my hardware to speed up the production of my final video.

Its quiet simple actualy. The setting in the Video Options is like the name says, for acceleration in the preview. That means to give you a smother playback when you are editing in your project. The other thing is the speed up of your rendering, your encoding, your exporting of the project to a final videofile. And depending on the chosing of the codec/container/fileformat some can use gpu hardware to speed up the export.

Still, that does not change the fact that its is obviously an issue with VP14 Build 270. I managed to reproduce your problem, so you are not alone.
And there is no reason to not use the GPU hardware for smoother playback in editing.

So i still would suggest to you to downgrade to Build 252 and file a ticket, if you dont have a real need for :

• Here are the patch notes for this update:
• Audio from ProRes 422 HQ files now plays properly
• Multi-channel audio files now show up correctly with new ProRes plugin
• Both channels of a stereo ProRes are now properly recognized
• The first frame is no longer repeated in renders to ProRes and HEVC formats
• Audio from 4k files shot with the Atomos Shogun 4K Recorder is now supported
• Audio from ProRes 422 files shot with Black Magic cameras now properly supported
• H.265 MP4 footage from DJI Phantom 4 Professional Camera Drone now supported
• The keyframe event "Set To" context menu operation of an OFX video effect now adjusts the keyframe value as expected
• Markers and regions are now properly saved inside the Trimmer window for ProRes and HEVC files
• Certain HEVC files that failed to load in previous builds are now supported

Addendum to above: I think I understand the difference now. For what it's worth, I experimented with Intel Quick Sync in my rendering profile. It definitely showed some speed improvement, but required that I have my monitor hooked up to the integrated graphics port (which I know there are work-arounds for, but isn't want I'm interested in at the moment). When I tried something like "use GPU if available", I saw no performance improvement in the rendering and noted that in the system tab I got the message "No GPU available". I thought this was all because I couldn't select my video card in the "Use GPU acceleration for video processing", but I now understand these are separate concerns.

So, what can I do if I see "No GPU available" in my rendering profile? (I also don't see any options for NVENC rendering profiles in my list.) Am I still in the same problem-space (of new card with older version of Vegas), or can something be done? Maybe I need to back and try the creative drivers after all?

In my first answer I gave you 2 possibilities that gives you what you aske for, and you can choose the one that suites you the most.
For myself I would choose the first option because with the new Magix AVC codec you are able to render much faster with very good results with as well the Intell GPU option QSV as the NVENC option of the Nvidia GPU.
My use is only NVENC, because with lower bitrate than the default ones of the default templates the QSV makes sometimes little faults at my hardware.

Exactly it looks like an overall problem of Build 270.
But you can also look for 'Allow Legacy GPU rendering' in the the General Options Tab. That should at least show of the dropdown menu in the Encoding Profiles to select 'Use CUDA if avaible'.

BUT that does not change the fact that newer drivers especially that one released 2 days ago is optimized for Video Encoding.
Since you spended money on a very new GPU, you should consider upgrading your VP14 to VP16 too.

NVEnc is far superior to QSV in quality. And since he has a new GTX1660 the included NVEnc profiles even encreased the Picture quality.
Now here comes a problem into play. VP14 seems not to use NVEnc at all but just CUDA as en enhancement options for faster rendering itself but not the NVEnc as the rendering system to A) encrease speed for rendering AND B) uses the hardware profiles of the NVEnc.

I made a little test in VP14 with a 10 second clip. Selected 'render with CUDA if avaible', took 20 seconds for it FHD 25fps.

I took the same clip into VP16, selected NVenc, took only 10 seconds.

Unfortunaly for my old Notebook GPU GTX960M does no new CRD exist, to enhance the NVEnc performance even further, but @eric-q has a brand new GTX1660, and its a shame he cant utilize the potential in editing AND rendering just because of an outdated Vegas Pro.

That's not a shame, it is an old program made before there were NVENC options available and the Cuda as an option was not what is should be and that's why the card makers stopped their developments.

In stead of a shame it is erics own choice made because he is a new user and uses as a beginner only version 14 Pro with options of former years.
