I want the sensitivity to feel the same as in QL in order to preserve muscle memory, but it seems to only change in steps of 0.25. 1.25 is too low, 1.50 is too high. The only solution that comes to mind is to use either 1.25 or 1.50 and change the FOV so that the distance I need to move my mouse to move my view one screen is the same in both games.

From my QL CFG:
seta m_cpi "800"
seta cg_fov "100"
seta sensitivity "9" (approx 1.3 without m_cpi).

Anyone here who knows the math that could help me?
