Agreed on Water & Mirrors and High Detail Lots, those two can be huge performance drains. As for the quality on sims and objects, for me that varies as to which world I am playing and how stressful its population is to the game engine; that's not very scientific or anything, but some of my worlds/households run much heavier than others. Most of the other settings I have on high or pretty high.
But my simming computer is seven years old now. It was suitable but mid-range (by TS3 standards) to begin with. It's never going to run like a more recent top of the line system and my graphics card is again suitable for TS3 but not what I would call high-end.
@Hejix - What kind of specs (processor, RAM, graphics card) does this new computer of yours have? Even if just off the assembly line yesterday, some systems are just not designed to handle the heavier EPs well, some will not do well with the game at all, others of course can take on a much heavier load.
