Anyone using NVEnc on Windows 7?

Please respond if you're using the NVidia accelerated encoding on Windows 7.

Thanks.

I have a i7980 1366 chip hex core I use to run media center. I could load it to it and see what happens. I have a older 2 gig Nvidia card in it that MIGHT suport it. It used to be my 10 pro 64 board till I upgraded to a 2011 board with a I7 4960x chip that is about 25 percent faster so I use that box to edit and recode on now. That one has a 8 gig 1070 card and supports it fine on 10 when everything is right.

OK, it loaded fine, H264 works very quickly, HEVC crashes immediately with a error. I have the option of using whatever encoder I want in 264 but HEVC says default only. The encodes I do get are fast and super clean when they work.

Thanks for the info. On Tools>Options>Hardware encoder what are the contents when you click on the NVidia Info button?

Well, it appears my old video card is too old to support HEVC according to what is in the box for it but here it is for you
- GeForce GT 640 : 3.0 , H.264:True, HEVC:False
- Processor: : Intel(R) Core(TM) i7 CPU 980 @ 3.33GHz
- Adapter: : NVIDIA GeForce GT 640, 26.21.14.3160, 2019-07-17
- Windows version : Windows 7 Ultimate
Maybe I'll have to dig up a newer card for it but I don't do my editing and recodes on it anyways but I can check and see if my geek buddy has a card that would work used in stock if needed.

Yes - I have been trying it with the latest 801 version.
I7-8700K . 32gb ram, AMD 5700 video (note VRD video hardware nvenc info says Windows enterprise when it is really windows Pro).
Currently re-coding windows media center wtv file to hevc and using 93% of cpu as shows in task manager.
The output is indeed a lot smaller but no one would notice the difference when viewing on television.
I wish i had a way to limit cpu use ..

The AMD 5700, being an AMD GPU, doesn't support NVEnc, so you're defaulting back to CPU encoding. There are a number of ways of limiting the CPU usage, probably the easiiest is to go to Tools>Options>Enhanced features and check "Reduce CPU priority While Saving". This will set TVSuite to run in a lower-priority mode using whatever CPU resources are available after high priority tasks use what they request.
