Players begin as a character in either 867 or 1066. Upon the death or deposition of a player's character they continue to play as that character's heir. Overall, players develop a dynasty over the centuries, with the game ending in 1453.

Crusader Kings 3 is a strategy game where you play as a landowner during the Latin holy wars. It's open-ended, and the goals are driven by the player, but most people play with the intention of creating an empire that's larger than any other on the map through subterfuge, war, diplomacy, or just buying everyone out.

As CK3 is a CPU-heavy game (lots of frequent calculations to do due to all the characters), that's going to be a real performance bottleneck. Originally posted by Razorblade: Your CPU and RAM are both quite lacking, hence why lowering your graphics did nothing.
