Raw Input

True raw mouse input (Windows). Reads unaccelerated hardware deltas straight from the OS, bypassing Windows pointer acceleration for 1:1 aim. Off by default because it genuinely changes how aiming feels: slow movement gets faster and flicks get slower than vanilla. Falls back to vanilla automatically if unavailable.

Reads mouse movement straight from Windows, before pointer acceleration, so a given hand movement always turns you by the same amount. Windows only; elsewhere it falls back to normal input on its own.

Turning it on

1. Sour Client menu, then Settings, then Input, where it sits as Raw Input.
2. Change any row and it applies straight away. Reset puts the section back to defaults.

Good to know

Every setting

In the order the game shows them. Indented rows only appear once the row above is set the way it says.
