m_rawinput
Removed in CS2: raw mouse input is always on.
What to use instead in CS2
In CS:GO, m_rawinput 1 made the game read your mouse directly. CS2 always does this, so the command was removed and typing it returns Unknown command. Nothing to change: your mouse already uses raw input.
Use sensitivity instead: your mouse sensitivity.
