@sigxo That's weird, because the videoconfig.txt in the saves games/respawn/apex should be the same for both EA App and Steam
try going there manually via the windows file explorer, and if you find it, check and see if the file is set to "read only" in the file permissions
i have mine set to read only because i disabled shadows via the videoconfig.txt and if i change a video setting in game, it will be reset when i launch the game mext time (because the videoconfig file is read only so no changes can be saved)
try verifying files in steam on apex
also, maybe a long shot, but if you copied the file path in the other person's message, you used your windows username right? and not your apex username (i know long shot lol)
