Question: how long does it take to adjust to a new sensitivity?
Answer: I played CSGO with 800 dpi and 5.75 in game sens for about 3 months, but all the pros recommend to use a low sens, so I bought a huge mouse pad (qck+) and lowered the sens to 1.125. I practiced the new sens with bots (in an aim map) for 40 minutes then joined a competitive lobby.
