This is major league bullshit tho.
On linux, where the config file for a specific program is, can vary annoyingly greatly depending on what distro you're using and sometimes the same config file exists in several places and somehow certain parts of the configuration parameters get taken from several of those files, so if you think you've found what the actual config file should be and remove the duplicates, suddenly the program uses defaults or doesn't even work at all.
Thing is, looking at some games, Horizon and Elden Ring being a prime examples, we can have both great games with great graphics.
You don't really want better games with worse graphics, you want better games that don't use great graphics as an excuse to bad gameplay.
