For anticheat, both BattlEye and EAC support Linux in userspace as long as the developers click the toggle to include the files needed, the issue is with other anticheat like Vanguard and with devs that just hate Linux users for some reason (Destiny for example). For everything else, I really don’t think it’s that much of an issue. Sure if someone absolutely needs Microsoft Office, then there isn’t much they can do if the online version don’t suffice, but Office suites on Linux are good enough replacement for the majority of people and are easy to use. For video editing, DaVinci Resolve runs natively, for Photoshop, there is a no-headache AppImage on github for Affinity running on Wine, but there is talks of it getting a native version (there’s also Photopea on the browser). For art, there’s Krita for drawing, Blender for 3D Modeling, Aseprite and Pixelorama for pixel art. For vector graphics there’s Inkscape. For game development both Unreal Engine and Unity run natively, and there’s also popular FOSS stuff like Godot. For CAD, FreeCAD is actually good now. For 3D printing, all major slicer software runs natively, etc.
