Eli5: your PC has different access levels a program can run at. This prevents a malicious or badly coded program from completely fucking your computer. Kernel level anti cheat runs at the lowest level access that exists under windows. It can do basically whatever it wants to your PC, and if a backdoor is coded in (happens way more than you’d think), it gives malware basically total access to your PC.

Oh, god. I remember how it ran on a stripped down gingerbread ROM lol.

I gave up and bought a new phone after that.

I’d say stock pixel Roms are a better experience than most custom Roms. That being said, if you have privacy concerns, grapheneOS is right there.

Personal choice, IMO. I don’t miss any of the features I gave up except for AI call screening.

It is a closes source program owned by an analytics company. I don’t know if there’s a good way to conclusively tell, but why else would they have bought it?

The good news is that running these games on Linux keeps them in userspace.

The bad news is that you are supporting this behavior.
