The client fps used to be in green color till yesterday and i used to get 150-250 fps , but today it turned blue colour and the client fps is in 80-150s

I stopped playing for almost a month, and when I came back (I did like 20 minutes of aimlabs and 5 deathmatches) it seemed like my ability to microadjust had vanished. I just end up firing right next to the enemy's head, barely missing it....

I think I parshly understood what it is. I think it's basically for having as much Map Control as possible and keeping a bunch of Options on where to plant. Please correct me if I'm wrong
