Re: Game launches to black screen, displays message about visual settings.

@StrwberryCalypso  Try launching Sims 4 in windowed mode.  You can do so by opening options.ini, which is inside Documents > Electronic Arts > The Sims 4, and setting fullscreen to 0 (zero).  If the game launches, you can then switch back to fullscreen mode if you prefer, but in that case, also change the game's resolution to 1600x900.  Both settings can be found with the other graphics options.

If this doesn't help, please run a dxdiag and attach it to a post.
