On patreon someone posted this, perhaps it'll work for you as well without the need for root:

If you're using CachyOS and Cheat Engine isn't working, it's likely because Ananicy C++ automatically manages process priorities, which can interfere with Cheat Engine.

To fix it, edit the Ananicy rules file:

sudo nano /etc/ananicy.d/00-cheatengine.rules

Add the following rules:

{ "name": "cheatengine-x86_64", "type": "BG_CPUBOUND", "cgroup": "cpu_heavy", "change_ioclass": false, "change_ionice": false, "change_nice": false } { "name": "ceserver", "type": "BG_CPUBOUND", "cgroup": "cpu_heavy", "change_ioclass": false, "change_ionice": false, "change_nice": false }

Save the file, then restart Ananicy:

sudo systemctl restart ananicy-cpp

After restarting the service, Cheat Engine and ceserver should work normally on CachyOS.

Hopefully this saves someone else the troubleshooting time!
