Question / Help Twitch stream have big lags

[Stiiks]

Hello everyone,

I am actually trying to stream on Twitch on Overwatch but when i look at my stream in my browser, it isn't fluid at all and have big lags. I have also a message in the bottom of the app that tell me that encoding is overloading. I've tried differents settings but it remain the same issue...

I have :
Intel Core I7 4702LQ 2.2GHz with Turbo Boost up to 3.2GHz
NVIDIA GeForce GTX 850M
12GB DDR3
120Go SSD
2x1To HDD

With the twitch connection test, it tells me than i have 1000+ kbits so i set 3500 max rate, I sa on forums that it may be too hogh so I decrease it to 1500 but still same issue. Maybe the fact that i use x264 for encoding cause some issues...

Can you help ?

Everytime i update i get lag after about 1 hour of streaming. Im stuck on 12.1 because every other version after that has caused me issues.

Can the stream lag beacause it encode with my Intel HD Graphics instead of my Nvidia GPU ?
