Question / Help Most optimised setting for my computer

Hi,

Is there any ways to optimise settings in OBS for my build so i can have the best performance/quality ratio when streaming?
Is CS GO there is a custom map for doing a benchmarks. I benchmarked my game without OBS and i get 160 fps average. With OBS i get 130-140 fps. I dont use x264 because i found heavier than NVENC.

Here are my spec:

CPU: AMD FX-8320 8 Core 3.5/4.0GHZ
GPU: MSI GeForce GTX 980 TwinFrozr V
RAM: 16 gb DDR3
SSD: Kingston HyperX 3K 120GB
SSHD: Seagate ST2000DX001 SSHD 2TB
HDD: WD Caviar Blue 1TB 7200RPM

download: 30 mbps
upload: 9 mbps

Here are the settings that i used for streaming:

And here is a video of my stream using those settings:

EDIT: The reason why i want to keep the highest fps possible without downgrading too much the quality is because i have 144 hz screen. I tested the performance on rainbow six siege and i get without obs 104-107 fps on average and with obs i get 98-99 fps on average so i guess the performance hit depend on the game but on cs go the performance hit is higher.

Thanks in advance.

Unless you're partnered, the "golden point" is 720p@30fps, 2000kbps. x264 is recommended, at a Veryfast or lower preset, as NVENC is an extremely poor-quality compression method meant to act as a band-aid for those with extremely poor CPUs which are too weak to otherwise stream. It looks terrible and will require more bitrate to look acceptable.

The 2000kbps realistic limit is based off of data released by Twitch a bit ago showing that most people can watch streams smoothly at that bitrate, and going higher will cause more and more people to buffer increasingly. Partners can get away with higher due to having quality options (transcodes) for those who can't watch at Source quality.

So you recommend me to try x264 720p 30 fps with 2000 bitrate. I applied those settings and i let the downscale filter to Lanczos. Should i use custom buffer in my case? Some people do not recommend to.

How to be a twitch partner to let users chose their settings for stream? Does bitrate affect performance? And i tried the settings that you recommended me and i found them pretty good when i benchmarked counter strike go i had 126 fps in average(still a performance hit for me but not that much for the better quality than NVENC) and 104 fps on rainbow six siege!

Build a community, have between 300-500 concurrent average viewers each cast, for the entire cast, do this for a few weeks to a couple of months consistently, then apply for partnership. It's hard.
Bitrate mostly affects quality rather than performance.

So i upgraded the bitrate to 2500 with still x264 720p 30 fps. If i upgrade to 60 fps should I tweak the bitrate at 3000?
