Usage:
/seta cg_atmosphericEffects 1
then do:
/vid_restart

Values: “1″ (displays) or “0″ (not displays)
Default: “1″

Note:
Setting cg_atmosphericEffects off helps (increases) your FPS (Frames per Second), so you will be able to see the movement smother. In the same time it reduces the lag.

Usage:
/seta cg_coronas 1
then do:
/vid_restart

Values: “0″ (on) or “1″ (off)
Default: “1″

Note:
Setting cg_coronas off helps (increases) your FPS (Frames per Second), so you will be able to see the movement smother.

Usage:
/seta cg_brassTime 0
then do:
/vid_restart

Values: between “0″ (off) and “3000″ (cartridges are visible long time after the shot)
Default: “2500″

Note:
Setting cg_brassTime off helps (increases) your FPS (Frames per Second), so you will be able to see the movement smother.

Usage:
/seta cg_shadows 1
then do:
/vid_restart

Values:
“0″ (no shadows)
“1″ (basic shaped shadows)
“2″ (contured but transparent shadows)
“4″ (very hard contured and dark shadows)
Default: “1″

Note:
Setting cg_shadows off (0) helps (increases) your FPS (Frames per Second), so you will be able to see the movement smother.

Usage:
/seta r_lodCurveError 250
then do:
/vid_restart

Values: between “0″ (always drop curves) and “10000″ (never drops curves)
Default: “250″

Note:
Setting r_lodCurveError to a smaller value helps (increases) your FPS (Frames per Second), so you will be able to see the movement smother.

Usage:
/seta r_lodbias 1
then do:
/vid_restart

Values: “0″ = high, “1″ = medium, “2″ = low, “3″ = custom
Default: “0″

Note:
Setting r_lodbias to low “2″ it helps (increases) your FPS (Frames per Second), so you will be able to see the movement smother. Also this low setting cuts out some small details from trees, so you can see through more easily.

Usage:
/seta r_dynamiclight 1
then do:
/vid_restart

Values: “1″ (singlepass) or “2″ (multipass)
Default: “1″

Note:
Setting r_dynamiclight to “1″ it helps (increases) your FPS (Frames per Second), so you will be able to see the movement smother.
Example: a rocket passing near you and lights the objects around it or explosions that give light.

Usage:
/seta r_flares 1
then do:
/vid_restart

Values: “0″ or “1″
Default: “0″

Note:
Setting r_flares off (0) it increases your FPS (Frames Per Second).
For example when you set a dynamite, you can see the dynamite light around it on the walls, or even through walls, so you know if it is set or not.

Usage:
/seta r_depthbits 16
then do:
/vid_restart

Values: “16″ or “32″
Note:
Setting r_depthbits to “16″ increases your FPS (Frames Per Second).
On some servers this setting is disabled, because it is considered a sort of cheat, giving you a possibility to see through walls in weird places/circumstances.

Usage:
/seta v_kicktime 0
then do:
/vid_restart

Values: between “0″ and “1″

Note:
When you get hit, your screen is moving horizontally and vertically a little bit.
Setting v_kicktime to “0″ stops this movement by reducing the duration to “0″ so you can see the enemy better.
Another setting might be: “0.500″ (possible default setting)
