Question / Help How to enable level 5.2 for stream 4K, 60fps?

[TryHD]

If you have 96% GPU load trying to do 60 FPS, you either need to reduce frame size, reduce quality options in-game, cap in-game framerate, or not do 60 FPS.

That will not help i would say ,at this point OBS is simply to inefficient. He does play in 1080p (so the game is most likely low stress for that GPU) and does upscale to 2160p.
Schapochka can try his luck with xsplit, if that won't work too, Geforce experience is the only way to do 2160p

Scaling down does not cost much GPU resources. A canvas resolution of 720p would be drastically more performant than 1080p. Every frame has to be rendered, and a larger frame takes more time. Downsizing is not expensive.

yeah whatever, 2160p is here the goal not 720p.

I feel like you have a very strong misunderstanding on how OBS and computer graphics in general work. Check our guide for more information here: https://obsproject.com/wiki/GPU-overload-issues

The reason that something like GFE does not have this issue is that they:

A) Have access to NVFBC, which is direct, on-GPU capture. This is exclusive to NVIDIA and Steam streaming as a capture method. NVIDIA doesn't let anyone else use it.
B) They do not composite (i.e. add different things to your scene with location, sizing, etc.), which means there is no additional load added to the GPU to render a scene before it can be encoded.

The hardware simply cannot handle playing a game in 1080p, upscaled to 2160p, rendering the scene in OBS, and encoding it all at the same time. Saying that OBS is "too inefficient" is not accurate at all here. It is OK if you do not understand how all the technical aspects function, but please don't assign blame where it is not warranted.

Thank you but you are very wrong, I'm pretty aware of it and that is the reason why i wrote what i wrote.

B) They do not composite (i.e. add different things to your scene with location, sizing, etc.), which means there is no additional load added to the GPU to render a scene before it can be encoded.

And here is the reason why he should use GFE if xsplit doesn't work.

With OBS, but like i said xplit does this more efficient at 2160p, so saying that OBS is

"too inefficient"

is very is accurate

It is OK if you do not understand how all the technical aspects function, but please don't assign blame where it is not warranted.

This backfired badly for you.

I'm sorry that you feel that way. Best of luck with xsplit!

I don't feel that way, it is simply a fact.

So you keep saying, but you have provide no evidence or explanation to back up anything, which I have.

If you wish to continue this discussion, feel free to PM me with your findings and testing methodologies. Let's keep this thread clear as it doesn't help the original poster.

All your posts in this thread didn't help at all, you can delete them and my replies to them if you realy want to help

I can't understand too, some of keys of latest NVIDIA GPUs.. I posted on devtalks some topic, but nobody answer.
https://devtalk.nvidia.com/default/...ding-with-hardware-requirements-of-streaming/
As I understood, nvidia didn't released GPU (no matter it's latest turing or pascal arc) wich can operate within 2160@60 on h.264.

Only h.265 supports can guaranted it. But, as I know, no one of streaming platforms doesn't support this encoder profile.

P.S. so only professional encoder hardware can do it.. And it will be work only if OBS support it
P.S.S. but I know 100% that all these gpus supports 2160p@30, because this is TVs' standard, not a gaming :\

Seems like outdated information by nvidia, they are able to do it.

look at this, it's not semi-planar contents. it's yuv420 for records. instead we use for streaming nv12(semi-planar). thinking it's not a GTX gpu
as I said before no one of gtx(turing inclusively) haven't 5.2 lvl in avc. And I don't know why, because oldest AMD R9 285(with VCE-3) has it..

It is helpful to start discussing. https://obsproject.com/forum/threads/capable-cpu-for-4k-60fps-streaming.93979/
