How do I know whats the correct sensitivy ?
cg_fov, or network settings , its kinda hard because sometimes i have iver 50 acc and sometimes i have 45,
i have my sensitivity at 1.8 sometimes for long range i change it to 1.2
it is a matter of personal preference, whateva works for you, you should use it.
my fov is usually 120, if i want to zoom in i have a script bound to my mousewheel that changes it to i think 90. again its a matter of personal preference.
as for network, i assume you mean cl_maxpackets.
mine are alwways on either 30 or 40 (depending on the server and my ping) because it can make u a tiny bit harder to hit.
