I took a look out of curiosity. These are the current top 20 games on SteamCharts.com, excluding a GTA V mod and Wallpaper engine and their ProtonDB rating:

Counter-Strike 2 [GOLD]
PUBG: BATTLEGROUNDS [BORKED]
Dota 2 [GOLD]
TBH: Task Bar Hero [GOLD]
Apex Legends™ [SILVER]
Path of Exile 2 [PLATINUM]
Bongo Cat [BORKED]
Rust [SILVER]
Slay the Spire 2 [PLATINUM]
Delta Force [BRONZE]
Don't Starve Together [PLATINUM]
EA SPORTS FC™ 26 [BORKED]
Dead by Daylight [GOLD]
Warframe [GOLD]
Grand Theft Auto V Legacy [GOLD]
Stardew Valley [PLATINUM]
Forza Horizon 6 [GOLD]
Grand Theft Auto V Enhanced [GOLD]
Destiny 2 [BORKED]
Overwatch [PLATINUM]

As you can see, only 4 of these are unplayable ("borked"), and 1 has a "bronze" rating. So the majority of the currently top-played games are playable on Linux.

Though Obviously that doesn't help you, if the game(s) you want to play aren't playable on Linux

Yeah every time I say this I always get comments like yours and I appreciate that you're making a point but it doesn't really help me.

I see Battlefield 5 isn't on there, because it isn't a steam game I get that, but my point isn't about steam my point is about gaming in general.

Edit: Battlefield 5 is listed as "SILVER", but reading the comments on ProtonDB it is unplayable in practice
