etconfig

The v_kickpitch sets the amount “player view pitch” changes when player is hit .

Usage:
/seta v_kickpitch 0
then do:
/vid_restart

Values: between “0″ and “1″

Note:
When you get hit, your screen is moving vertically a little bit.
Setting v_kickpitch to “0″ stops this movement so you can see the enemy better.
Another setting might be: “0.600″ (possible default setting)
