1050 user here, it works fine with VP 19.458 and there is a noticeable performance drop if you disable it in options/preferences/video. Try installing the latest NVIDIA Studio driver (I'm on the January release).

If it still doesn't work try resetting Vegas: https://www.vegascreativesoftware.info/us/forum/faq-how-can-i-reset-vegas-pro-to-default-settings--104646/

You should see the GPU in preferences/video, preferences file i/o and with NVENC render options when you go to render.

I got the Nvidia 1650 and everything is working fine now.

Since I upgraded to Vegas 19 Pro (build 458) my gpu processing must be turned off because it does not work ( Gigabyte GEFORCE GTX 1050Ti). Under 18 it worked fine. Other application does use it without any problem. What has changed in Vegas 19 to cause this problem?

The video card has the best driver installed (the computer informs me)

I realize that this has been resolved by replacing the 1050 with a 1650, but thought I'd comment that the "computer" may be giving false information, depending upon where it's figuring this out.

I've seen some driver update utilities that seem to automatically select the 'Game ready' driver rather than the Studio Driver, which is more suitable for the GTX 1050ti to work with GPU acceleration and AI applications.

The Studio drivers for Vegas have been recommended here several times by the developers.
The game-ready drivers are updated more often because this is mainly required for the games - but the Studio drivers are supposed to be more stable.

Could you tell me where can I find these driver recommendations by the developers? I have been using Vegas for quite a long time but I never joined this forum before so I am sure I am missing a lot.

Thanks for your comments.

@Gabor-Finta Hi, try this link, download Geforce experience, that has a tab to check drivers, https://www.nvidia.com/en-gb/geforce/graphics-cards/gtx-1650/

It also has the option Alt+F1 to screen grab a picture, or Alt+F9 to record the screen, & some other bits,,,

Or you can click on Help at the top of Vegas, Check For Driver Updates,

@Gabor-Finta
This is the first info I found - I'm sure you'll find more in the forum search.

@Gabor-Finta Have a 1050ti in my laptop and works fine here with every version of Vegas 16 through 19. But my situation might be because the laptop also has an Intel igpu which I select for decoding on the I/O tab. My driver versions are Nvidia 511.09 Studio and Intel 27.20.100.8935.

Using the Intel CPU for decoding was working for me as well but as soon as I added the gpu, everything came to a halt.

You probably just had to reinstall drivers for 1050ti, if it was incompatible with VegasPro19 then that would mean all the other pascal cards would also be incompatible such as 1030/1060/1070/1080/1080ti, but that's not true. Only card that's a bit different is 1050 because it doesn't have hardware decoding or encoding, but with a compatible intel IGPU that still be ok for VP19

EDIT: Incorrect info about 1050 and 1030, see RogerS post below.

GTX 1050 has hardware encoding and decoding, you're thinking the GT 1030?
