Forgot that i found more related addresses.
0x858CEC - Aiming Recoil Multiplier (float, default 0.04)
How much recoil increased/crosshair expands per shot (calculated with data from weapon.dat)
Set to 0.0 to "freeze" crosshair.
0x8D2E64 - Aiming Recoil Cooldown Multiplier (float, default 0.96)
How much recoil "decreased" / crosshair retracts.
Set to 0.0 for instant cooldown. 1.0 to disable cooldown. More than 1.0 to make crosshair expand indefinitely.
I'ts possible to make every value independent?
I mean, have just the "static" crosshair, but with the bulletspread value intact?
Locking up the crosshair but keep the recoil?
Sorry, I don't know how. Haven't been looking into it.
