In CSGO, 75% of pros use 4:3 aspect ratio whereas only 10% use 16:9 and 16:10 has 9% pro usage. Source: https://prosettings.net/cs-go-best-settings-options-guide/

4:3 in Valorant only stretches your HUD but it does not reduce your field of view. Yes CSGO 4:3 pros seriously prefer 4:3’s lower FOV compared to 16:9.

Of those 75% 4:3 pros, 75% use stretched because they prefer the wider player models (hitboxes don’t change) whereas 25% use black bars.

So why doesn’t Riot allow real 4:3 FOV in this game?
