i know, that's why i mentioned it. i don't mind losing out on games with kernel anticheat. if you really do want a big battlefield shooter, battlefield 4 is still an option. if you want something smaller then maybe you can try the finals, which also breaks free from the hero shooter genre a little. if you do want a hero shooter then marvel rivals also works on linux. i don't think you're missing out on a lot. maybe battle royale shooters? fortnite, pubg and cod warzone won't run on linux, but to some that's also a benefit.
