That’s because the anti cheat is running in a fake kernel with Proton. Developers have ways of detecting when the kernel isn’t real… Sometimes… But the Helldivers devs don’t seem to mind for now.
I don’t know where the hell you got that information but that’s not how proton works. There is no “fake kernel” it’s not a virtual machine or an emulator it’s just a translation layer that translates Windows syscalls into linux syscalls
Yes, and part of these make the anti cheat believe it’s running in a kernal.
None of the things needed for a true kernel level anti cheat are in a translation layer, some of them just can’t be. It’s why games with actual kernel level anti cheat have never worked in proton and never will. Historically the only way to play those games is either be on windows or use a vfio virtual machine (which also probably won’t work even with tons of vm hiding techniques depends on just how sensitive the ac is) . Wine/proton simply can’t translate the upper parts of the nt kernel needed for it.
If the anti cheat is working in wine/proton it’s not kernel level
The syscall translations that would go to the nt kernel, can be seen as a “fake kernel”, no?
Wine has a process that works as a substitute for the Windows NT Kernel. How that works in detail, which calls are abstracted with an internal model, and which are mapped on to Linux kernel calls, is a bit silly to get hung up on, no?
I think it’s perfectly fine to call that concept a “fake kernel”. I don’t know what you’d need in order to qualify more?
just a translation layer that translates Windows syscalls into linux syscalls
“Just”?. No. It also has an internal model. Which system calls end up as Linux syscalls, and how, is not a stateless translation. The NT kernel is modeled. And although you are right in your straw man argument that it isn’t a “virtual machine”, or an “emulator”. Neither of those are a requirement for the concept of a “fake kernel” either. Seems a bit rude to go so balls out hard against it, as you did.
