Question about Graphics Card

Alpine and other beautiful custom worlds of its size and complexity are too large a world for the game engine to handle for most of us. Although it does require a strong system to play on properly, it's not strictly our systems that don't like it. It's either going to balk, sputter, crash, and/or Error 12 on you right at the outset or it's going to wait until you get all comfortable with it in an ongoing game with the sims in the world progressing through their lives as you wanted them to and then do the above. Not sure it's really any better that the issues arise a bit later rather than right away. Honestly I would just set that world aside or perhaps use it as something to admire and maybe emulate some of its areas in other worlds, but on a much smaller scale.

Certainly by all means delete the cache files, this should be done on a somewhat regular basis anyway -- this means the five files on the top level of the TS3 user game folder in Documents, not necessarily any of the others. But I'm afraid I don't recognize this issue when it comes to EP content unless also you have CC that is only meant to look like the content and that is what is getting in the way. If all else fails, you may need to consider removing and then reinstalling Showtime, but it may not work out any differently the second time.
