Re: Sims 4 looks grainy

@cocoawhirl  Try turning Edge Smoothing to its highest setting and checking the box for uncompressed sim textures.  Quit and reload the game after making the changes.  If you don't see a difference, switch to fullscreen mode and quit and restart.  The next step would be switching from DirectX 9 to DX11 mode, or vice versa.  Here's how:

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