Here are my specs of my pc:
MotherBoard: ASUS ROG CROSSHAIR VI HERO ATX
CPU: AMD® RYZEN™ R7 1800X
GPU: x2 NVIDIA GeForce GTX 1080Ti GPU W/HBB Bridge
RAM:Extreme DDR4 2666MHz Memory - 32GB
Power Supply: Corsair AX1200i Modular Power Supply
HDD: Seagate Barracuda 1TB - 7200RPM 3.5" HDD
SSD: Performance NVME M.2 256GB
Monitors: 3x 27inch BenQ 144hz 1ms

My goal is to stream on twitch 1080p 60fps. Yes i am a partnered streamer and i do have a 2nd pc to stream off of and use this as my gaming one if need be. anyway, if anyone can help me optimize on obs studio that would be a huge help! ive done research and ive only seen negative comments in regards to streaming on twitch in 1080p but i believe that to be ridiculous especially considering i have the hardware for it.

Welcome!

With your specs, I think you can use the x264 encoder without no problems. Just set the bitrate to a range from 2000-3500(or 3000 max).

Yes, though don't expect great quality like a recording. The bitrate range I have mentioned is the Twitch recommended bitrate, so you should know that if you're a partnered streamer.

Yea but I usually ran 6k bitrate. As a partner we get access to more options for bitrate I believe which allows us to push it further. I was just wanting to ask for some guidance. I'm looking for the best quality of the stream as possible. Highest resolution, for 1080p

You should take a read of this:

https://www.reddit.com/r/Twitch/wiki/guides/equipment/bitrate_resolutions_quality

I think that you'd be better doing 720p (or maybe 900p) at 60fps with a bitrate of 6000 if you want good quality. If you push the resolution higher the quality will start to degrade because there is too much data especially in FPS style games with high motion.

If you are using a streaming PC (I hope you are) then the other thing you can do to improve quality is to change the CPU Usage Preset in the Settings, Output Tab. I use Medium which gives better quality at the cost of CPU usage, if you have enough CPU then Low would really help with the quality and you may be able to ramp up to 1080p but don't hold your breath.

Chiming in, I agree with @Xsoulsin that Twitch does allow up to 6K bitrate, but that doesn't mean every user can watch the stream. I mean, if you output your stream at 1080p60fps with 6K bitrate, IMO the number of people watching you might dwindle since not everyone has a blazingly fast internet.

If you don't believe me, Jack0r made a thread about this.

You did read his initial post, didnt you? He is a Twitch partner so he has transcoding anyway. 1080p60 with 6k Bitrate is a great figure to start with and a Ryzen 7 1800x System should be capable of streaming 1080p60 at least as a streaming machine.

We're going to need log files to see what your Ryzen 7 can do. That CPU is still too new to know that it should or shouldn't be able to do 1080p60 at any given preset, so until you post some log files of your attempts, we can't really advise you much.

As far as the bitrate thing goes, as a partnered streamer maybe you can go beyond 6Mbps? If not, then these guys might be right, you might be well advised to stay at 720p. But that depends on a lot of things, such as what your content is.

I have recently built a streaming PC in a dual PC setup. Given current max bitrates at 6k, most still recommend for picture quality to stream at 720p/60 or max 900p/60 like a few streamers changed to when bitrate maximum changed from 3500 to 6000.

Currently streaming at 3500 bitrate at 720p/60 and using the x264 preset SLOW allows my Ryzen 1700X OC to 3.8 with 32 GB DDR4-2666 memory to have average CLU load hovering around 20-25%. From my initial research, presets beyond SLOW are negligible for quality vs the increased load on the CPU.

I highly doubt that the Ryzen 1800X is unable to encode 6k 1080/60 under a reasonable setting for x264 (How good it will look is another matter and subjective). Try the auto-config wizard in the new Studio for some initial settings.

Ah, I didn't see the transcoding part. My fault, sorry!
