A week ago they made an announcement referring to anti cheat improvements. Today, a couple of friends on Windows noted that the game no longer launched with AutoHotKey enabled (no malicious use cases, just using 60% keyboards) as of last night's minor update.
Since the game is deck verified, I'd expect respawn will resolve this soon enough.
Perhaps they were looking at people using SnapTap and similar technologies, which were recently banned in CS2.
I feel like analogue / hall effect switches can lend a player a substantial advantage in apex when it comes to strafing. I wonder if they've tried to mitigate that.
small update - there's been a minor (17.4 MiB) patch to Apex since. Could be worth checking in with it to see if it has resolved linux compat,
Edit - it's working for me on Fedora 40 Workstation. NB that I've never hit the original anticheat issue to begin with, and I use the following launch command to run the game under VKD3D (mostly AoT shader compilation) along with suppressing launch splash screens / videos and presenting Mangohud
So sad that they didn't fix the AC until the game had been around for years, I would've loved to play it in the beginning when the player skill was more varied. Tried to get into it when Linux was allowed but it seemed like mostly the try-hards were still playing. Had some good games but it was a bit too sweaty for my friends at times.
I tried playing it through Wine during season 2 or 3, the game worked flawlessly but you would get kicked after 1-5 minutes due to missing AC.
