I have a razer mamba TE however I don't know what my DPI and sensitivity (in-game) should be for CS:GO. The pro players have a DPI around 400 and a sensitivity of 1 to 2 however when I apply their config, the sensitivity is way too low. Used to have a very old mouse which didn't have a custom DPI and my sensitivity for CS:GO was 8. What should my DPI and sensitivity be?
