Question / Help Need help with OBS settings to stream CSGO

[SperacyCSGO]

Hi everyone here,first time using this forum.
My specs are;
Windows 10
16GB Ram
GeForce GTX 950
i7-6700 @ 3.4GHz

I've tried a few bitrate/buffersize settings,different filters,fps settings but my stream looks choppy.
My in game fps is always fine tho. I'm not sure how to tweak the OBS settings to get the quality i want :/
