I noticed that on pc, steam controller can't do mouse emulation. Likewise, steam link and moonlight can't stream mouse input on to the game either. Most likely 'emulated' mouse input is being blocked by the drm. But on steam deck, using the track pad and gyro as mouse has no such issues. I would guess that the drm running in proton does not go deep enough to intercept the emulated mouse and can't block it. If that is true, one might be able to use linux/proton to cheat, rendering the whole point of the rootkit drm useless.
What's the situation with the DRM? I've not heard much of this, but a quick search shows that it's causing a lot of crashes, which isn't super uncommon for a newly-released game.
Kernel level anticheat has access to every corner of your machine. It's basically begging for someone to abuse it internally or someone to hack it externally. Etc..
Wow I was completely unaware that this game had something so invasive. I'm definitely going to have to refund it. This sucks since the game is really fun but that's a deal breaker for me.
