Because save files go on the cloud, like with Steam, they’re meant to be transferable to a different machine. You don’t want settings saved on one machine to be ported over to another, when the player decides to install on a different PC. Those settings are there to make the game run well on that particular computer, hence the whole point of all the ini files. But I guess Epic just doesn’t want to give us the functionality when it comes to changing and saving certain console variables.
