Most is a stretch.

The FPS in the top 100 currently most popular games on Steam[0] and their status [1]:

  #01 CS:GO - native
  #04 PUBG - anticheat
  #05 CoD MW2 - anticheat
  #06 Apex - Works (it has anticheat that works on Linux)
  #07 TF2 - native
  #09 Rust - Works
  #12 Destiny 2 - anticheat
  #21 Rainbow 6 - anticheat
  #22 DayZ - Works (it has anticheat that works on Linux)
  #26 Warframe - Works
  #69 Payday2 - Works
  #78 Arma 3 - Works (it has anticheat that works on Linux)
  #79 CS:S - Native

Native or working: 9/13

Broken: 4/13

Non-steam or outside top-100:

  OW2 - Linux is second class and not actively supported - but Blizzard have unblocked Linux support when issues were reported

I'm probably spectacularly unlucky as I play Siege, Destiny 2, CoD MW2, Hunt Showdown (#63), and the occasional Fortnite (EGS) and Valorant (Riot), none of which work.

Battlefield 2042 is on Steam but not supported, though I'm not sure if that's the anti-cheat solution or Proton.

Sadly even a few top games not running on Linux is enough to keep most PC gamers off of Linux.
