Скачать или смотреть Improving visibility in CS:GO with movement binds.

It's just a null-cancelling movement script created firstly by a nub on a mission for TF2.I put here "r_cleardecals" to remove some "particles" like blood and black area after the nades explosions.
It helps to improve visibility a LOT.Might increase your FPS matter as well.But haven't tested the benefit.
Leave me a like if u enjoyed actually:)

bind w +mfwd
bind s +mback
bind a +mleft
bind d +mright

alias +mfwd "-back;+forward;alias checkfwd +forward;r_cleardecals"
alias +mback "-forward;+back;alias checkback +back;r_cleardecals"
alias +mleft "-moveright;+moveleft;alias checkleft +movelef;r_cleardecals"
alias +mright "-moveleft;+moveright;alias checkright +moveright;r_cleardecals"
alias -mfwd "-forward;checkback;alias checkfwd none;r_cleardecals"
alias -mback "-back;checkfwd;alias checkback none;r_cleardecals"
alias -mleft "-moveleft;checkright;alias checkleft none;r_cleardecals"
alias -mright "-moveright;checkleft;alias checkright none;r_cleardecals"
alias checkfwd none
alias checkback none
alias checkleft none
alias checkright none
