Im starting to play osu mania. What tips could be useful to improve?

For the first time in a long time I asked someone to hangout and I almost got laughed at. I'm so cooked man

I think i've figured out how to play Lazer and make it feel like osu stable:

1. Change your Renderer from DirectX 11 to OpenGL

2. Ajust the framerate as closest as your monitor framerate
(ex. 75hz ≈ 150fps so I don't get so much screen tearing) - - -

Some other osu stuff

First post here :D
