Might be me kicking in a open door for some but just tryed the classic crosshair/viewmodel and it feels alot better for me, as a old 1.6 player.
This is basically the standard crosshair and viewmodel for CS:GO.
But by changing the crosshair and viewmodel to classic you get this.
For me the viewmodel feels more like a pc view instead of the console (cod) view and the classic crosshair feels alot better for cubing in those heads for those headshots.
I'm really liking these settings after just trying them out and although i've been playing cod for the last 5 years these just work for cs.
