Tips on Quality?

Talking about video quality, I can deal with audio and overlay quality So, I recently started using OBS and can't seem to get the quality quite right. I was wondering if anyone could help me out?

P.S. I'm not worried about people stealing my sh**ty content, the reason I have a "logo" is because I don't like the video replay editor in that corner while recording. I'll eventually get a better overlay, which won't have my "logo" on it.
