When hacks exist that use FPGA's to MITM PCI-e level data, I'm not sure what else you can do. The problem contradicts itself: You want a secure, unhackable game, but without essentially root/kernel access?

Heuristic-based anticheat seems to have fallen out of favor.

I honestly believe we should return to dedicated servers + admins. This hacker/anti-cheat arms race is never going to end.

there is an immense difference between obfuscating the binary you ship for your game and requiring rootkit-level anti-cheat systems to play your game.

it is wild to imply they are remotely the same in their effect on the user. one is literal malware, and the other shares 0 of the capabilities or effects of malware.

They do employ former malware writers to work on some of this stuff from what i hear.
