it's a delay or FPS issue ?

Hello everyone ,

it's getting more and more serious about this issue

well, when playing in both 64, 128 tick servers and facing a real problem that the only logical thing that can describe it's a "DELAY" issue related

i play usually with 70/80/90 latency which is probably the average ( still playable anyway), but i feel like the most of my enemies have a time advantage, once i peek i get headshoted easily sometimes they pre-fire, and no its not related to reflex time , i'm actually Legendary eagle and all my friends are globals and SMFC (played with them back in 1.6 and i guess that i'm good enough to play versus skilled guys than LE rank, even in casual (where it's really rare to see very good players ) i get killed easily by some low players with slow movements , it's like the enemy have enough time to react and +attack , unlike me

FPS : 80/70 average monitor frequency : 75/85/100 depends on the resolution (mostly 75 )

i don't really know if it's FPS related or FPS + hitbox ?? ( i shoot in front of the enemy model but only his left side for example get fired : lag_componsation ??? )

if you have any idea please share .. or any command that can reduce this issue
