Question / Help No NVIDIA NVENC settings in OBS?

Hello all,

Currently I am having problems with high CPU usage while recording, which lead to slower loading times in PC games and slower emulation in emulators, and as a speedrunner this is not good. I searched online and found that NVIDIA has their own encoder of sorts, the NVENC. However, looking into OBS, I see no option for this, only the default x264 (too much CPU usage) and the AMD thing because I have an APU, but that encoder doesn't even work because I have no monitor set up to it. My NVIDIA GT 730 should work because it's Kepler architecture is supported, but again, there is no option for it in OBS. Is there another factor I'm not accounting for that makes my GPU not supported?

If your nvidia drivers don't expose that your card supports nvenc, obs never sees that your card supports nvenc.

How do I see if my drivers expose that my card supports NVENC?

Well, I mean, obviously they don't, but how do I make them? My card fits under the specs.

I still can't find out if it's Fermi or Kepler. I got a snippet of CPU-Z and it says it is the EVGA rev. A1 of the GT 730. Checking this out online it also says nothing about Fermi or Kepler on this page: http://www.evga.com/Products/Product.aspx?pn=02G-P3-3733-KR, although it kind of hints at it being Kepler in the model number, where the last two characters are "KR", maybe a acronym for Kepler? I'll post a log right after this.

Okay, here's the log of about two seconds of recording (sorry if it's long, I don't know what's necessary and what's not):

It has one error: "LoadLibrary failed for 'nvEncodeAPI64.dll', error: 126" But to be honest I have not seen that error before.
By the way, does Shadowplay work, have you tested it?

It says in GeForce Experience that it is not available, due to the fact that it is not a GTX card, so I have not tried Shadowplay.

Okay, problem solved, there's apparently two versions of the GT 730. There's a Fermi version and a Kepler version. What threw me off was that it was widely accepted that the 2gb version was Kepler, but that's not the case for my 2GB card. When buying a GT 730, make sure that it has more than 96 CUDA cores, because that's the Kepler version.

Thanks for the help!
