I played Assassin’s Creed Origins during a free weekend a few years ago and it automatically set its own graphics settings and dumped you into the game without being able to access the menu so it looked like my screen was covered in patrolium jelly half the time. About an hour into the game when I could finally access the game menu I learned why. It set all settings to their absolute highest but resolution scaling was enabled so it was trying to render graphics my PC couldn’t handle then internally reducing the resolution down to 360p or so. Once I dialed in settings that my computer could actually handle without resolution scaling it looked a million times better
