One of the issues that gaming on Linux has right now, and one of the main reasons why Windows is still the dominant platform for gaming, is because there are still games that resolutely will not work on SteamOS or any other Linux-based distro. And one of the main reasons for that is a lack of support for some of the biggest anti-cheat software in use today, specifically the kernel-level ones.
That means you get no Fortnite, you get no Battlefield, you get no Valorant, you get no FC26 (okay, that one's just for me). Nvidia gets this and has been explicit in the announcement of the new Arm-powered RTX Spark "superchip" for Windows on Arm that is working hard with all the leading anti-cheat developers to ensure the software works out of the box on its systems.
