Question / Help Mimic Nvidia Share in OBS Studio (Quality & Performance)

[Ca9ine]

Evenin'!


First off, I must say:
OBS Studio is amazing! Everything it does, and is- for free! Thank you so much!


To my question(s):
Can I mimic Nvidia Share's performance and quality using NVENC in OBS Studio?
I can not for the life of me seem to figure that one out. Some NVENC settings are most likely above my know-how.

Using Nvidia Share, I go 1080x1920 @ 60 FPS smooth as butter and an amazing quality during my streams, and close to no performance hit at all on in-game FPS or any other areas on my system.

Using OBS Studio however, I don't come close. I stream 720x1280 @ 60 FPS- it's still smooth but overall quality is much lower, and the performance hit is significant. 1080x1920 @ 60 FPS even more so.

Bitrate is the same in both, I've even tried upping it in OBS but it stil doesn't compare to Nvidia Share.
I should mention I disable preview and minimize OBS as I stream too.


Does anyone have experience with this? Is it a lost cause, or am I missing something?
There are settings under NVENC i simply don't know what does. Fiddling with them just makes OBS simply not allow a stream to start.

I really want to use OBS over Nvidia Share. OBS Studio has everything I want and more, Nvidia Share is very limited.

I can't use X,264 because of CPU limitations.
QuickSync is unsupported from my motherboard.


CPU: i5-2500K
GPU: ASUS GTX 970 OC Direct CU II STRIX



Thanks!

Hi,

Can you post your obs log, the details on how to do this are forum as a sticky, also post your nvida share settings e.g bitrate etc.

Thanks for the prompt reply!

Logfile as follows: https://gist.github.com/733561006d9fe0cea60f3b678974f15a


Nvidia Share bitrate 60 FPS @ 5000
I have tested both Nvidia Share and OBS with 5-8k

Nvidia Share is even more fantastic at 1080p @8k
OBS Studio with NVENC not so much :(

Set OBS back to use the Direct3D11 renderer and disable multi-adapter compatibility in the game capture source.
Also use simple output mode, set quality to indistuingishable and the encoder to Hardware (NVENC) (for streaming just switch the encoder to NVENC)

Yessir!

I will do this as soon as I get a chance to and test it.


Thank you for the direct approach and replies.
Excellent support!
