Don't wanna be an ass but you said "aren't pros" but then said "jasonR always used 1080P on his pro days"
Idk why you guys can't just agree to disagree, both have benefits.
4:3 stretched does make models easier to hit, they're the same pixels but take up more space on the monitor.
16:9 give you more vision, clearer picture, more precise models.
Pros use what they are used to, pretty sure Guardian uses 4:3 black bars 800x600 lel, and he's one of the best players in the history of csgo. Just chill out and play the game and stop yelling at each other
