Battleye has integrations with Proton as well, but as with EAC, it's opt in by the developer, and not every dev enables it.

Sure - leads more to my point of... check the games you care about for support. I didn't really want to start itemizing these things.

Most AC used in the competitive Counter-Strike community isn't supported, for example. Only first-party VAC.

It depends on both. Anti-cheat used by Destiny 2 is supported, but Bungie needs to allow it first.

Indeed. I meant to imply both if I managed otherwise. This is just a casual warning - Linux gaming is great [as much as the industry allows]

I've had some luck with the Windows VM approach instead. One may have to disable quite a lot (ie: Hyper-V enhancements) to truly trick them.
