DP doesn't need any adjustments, its just some basic fps settings (OBS).
Usually, if you don't have streaming op machine (and really good internet) you wanna aim for bitrate around 2k, using 2200 atm + custom buffer (the lower, the lesser chance for dropping frames, running 1k custom buffer now). And probably 2nd and last important setting is in Advanced (assuming you are using OBS) x264 preset, use Fast + encoding quality High, because it helps your quality a lot
EDIT:I am at lecture atm, i can help you set it up through steam for example if you want. SShoting my OBS settings, I am pretty proud at(no idea what word to use lol) my steamy quality ^^
