New NVENC(2gpu one for streaming one for gaming?)

[Zeketo]

New NVENC for streaming just came out and it claimed to be better than fast preset in h264 and better than medium if you set to a higher quality..

I just test it with my 1070 and it works great. The fps gets much higher comparing to what I get with h264 and also I am able to get a much better quality for my stream.

Is it possible to use one gpu dedicated to stream only and other one for gaming?

If that works, I am finally now able to stream without any quality concerns(bitrate and res) and with no fps drop whatsoever.

I mean its huge.

If this works, it means everyone can just get another gpu without setting up another streaming pc and basically getting the same result. I will be happy if I can stream any game on 1080p 60fps 6000bitrates on fast preset even with no fps drop (medium is my dream tho)

Something you're missing is that GPUs doesn't use CUDA for NVENC, it has a dedicated processing core (Titan XP / Xp / 1080 Ti have 2) to handle it, so having a dedicated card for it should in theory provide the very same performance.

 

Now what you could do is get a turing card like the GTX 1660 Ti which has an improved NVENC processing core that's noticeable more efficient than Pascal's.

There's no point in doing that. Just use the one and same GPU both for streaming and gaming.

My goal is to get the same fps while streaming as not streaming. Will I be able to achieve it by adding a dedicated gpu? I am not aiming for the insane quality. I wanna get the same fps with some decent quality settings in obs

If you use NVENC you will not have lower FPS since it's a seperate part of the gpu that does the encoding from the part that does the gaming

If you use NVENC, you'll get the exact same performance with two GPUs as you would with one GPU.

They don't use their CUDA cores for NVENC encoding, so NVENC has no bearing on your FPS.

 

I can stream Destiny 2 from my GTX 780 and use NVENC encoding, I get exactly the same FPS as I do streaming that I get playing normally.

Oh I get what you guys are saying now. 

So using NVENC doesn't impact gpu gaming performance by any bit?

While not quite the same thing as I have a GTX1080, I've lately been streaming my gameplay on Twitch -- Tropico 6 for a couple of hours today, w00t! -- and I can totally attest to this. It doesn't change my performance a single frame per second in either direction.

That's insane. I should do my research a little bit more.

But why do I feel laggy when I am streaming?

is it maybe because obs take some of the cpu usage?

I feel laggy when I am streaming apex. It didn't feel as smooth as I am playing when not streaming

Are you talking about network-lag or framerate-drop? Two entirely different things. Streaming consumes your internet-bandwidth and if you don't have enough upload-bandwidth, you'll see network-lag in online-games.

I believe gtx1080 has 2 encoders on its NVENC chip just like 1080ti. I was just going through my research on this and find out about this

I am not 100% sure tho. I am certain that its not as smooth as not streaming. I think my internet is fine and consistent.

Does this improve streaming to twitch? I've heard that NVENC is not so great for twitch streaming and I have a friend of mine with a 1050 to and i5 and she'd rather not use the i5 because it's barely enough.

That answer is useless. I need to know if you're talking about lower FPS or not.

You need to use a tad higher bitrate than if you used software-encoding and that has not changed, but e.g. I stream 1080p 60FPS at 6Mbps bitrate just fine. The streams look perfectly watchable and all.

 

I only just enabled the option to store the streams on my Twitch-account, so there aren't all that many clips there yet, but you can view what there is at https://www.twitch.tv/werecatf/videos and see for yourself.

Does increasing bitrate or 60fps for stream impact the usage of cpu during streaming?

I still dont fully understand the whole thing.

If the NVENC is only using NVENC chip in a gpu to process the stream, is turning up my obs settings going to affect my gpu or cpu performance at all? lagging etc

1080p 30fps or 720p 60fps are both tolerable (even 720p 30 if need be, based on her internet speed) but we've had some trouble making it work. Hopefully this improvement helps

No. Increasing bitrate does affect your Internet-bandwidth, though -- if you don't have enough bandwidth, you will lag. It has nothing to do with CPU or GPU.

I mean I am pretty sure increasing bitrate will increase cpu usage for obs and thus drop frames during games. That sometimes could be the difference between a smooth gameplay and choppy one.My fps is lower in games when streaming.  I think it might be that 6% cpu usage on obs.

Why do you keep arguing about this? You've been told multiple times now that no, bitrate does not affect anything as long as you use NVENC and your Internet-bandwidth can handle it. You can damn easily just go and test it yourself.

You have not said what settings you use or given any useful information whatsoever about your setup, so there's nothing to be said here.

I've used nvenc with my 1080ti and have never noticed a performance drop from it. It's pretty much a win win, and if you're starting out streaming the quality of nvenc is fine.

what game do you stream, did you try apex?

[Mick Naughty]

As there are a million variables to this, FPS may not be effected but gameplay can. 

 

Which is why a 2 pc setup is superior. Need to go for minimal system impact without a huge loss in quality. 

 

Need to adjust the settins in obs if you are set on using it. You are also limited on what something like twitch will except on bandwidth. So could be wasting effort to an extent. Should just do shawdowplay using nvidia, it’s pretty nice and has great quality.
