30 fps was not the norm, at least not with competitive games. Like Counter-Strike in 2000 on a CRT. Yes 1024x768 was common, but at 100 fps. Alternatively you would go to 800x600 to reach 120 fps.
It’s only when LCDs appeared that 60 Hz started being a thing on PCs and 60 fps followed as a consequence, because the display can’t show more anyway.
It’s true that competitive gaming has pushed the priority of performance, but this happened in the 90s already with Quake II. There’s nothing fake about it either. At the time a lot of playing happened at LANs not online. The person with the better PC got better results. Repeatedly reproduced by rotating people around on the available PCs.
