The Sims 4 - The trees in my game looks blocky

And have you been able to solve the problem in the meantime? I have exactly the same problem, but only with trees in Windenburg. 

@Naluyaki  Please test with no mods or custom content, as in, move the Mods folder to the desktop and delete localthumbcache.package.  You don't need to save your progress.

@Naluyaki  Do you see the issue in a new save as well, or just in your current one?  Does it change with the seasons?  You can at least choose a season to start out with in a new save.

Please also run a dxdiag and attach it to a post.

Unfortunately, it's hard to see in the screenshots. But I've marked the type of tree in question with arrows. No other tree is affected, in any world or neighborhood. Only the one type of tree in Windenburg.  

When you pan the camera, move around the environment as a Sim, etc., you can obviously see that the trees are not in 3D.

@Naluyaki  A lot of assets in Sims 4 aren't really 3D if you pan out or zoom in on something that's supposed to remain in the distance.  That's not a technical issue, just the way the game was designed.  This particular thread is about sets of leaves looking like they've been drawn on sheets of paper.  Please have a look at the screenshot attached to the first post on page one.

If you do have the same issue as in that first post, please take close-up screenshots.  And in that case, I need the full dxdiag, attached as a text file, not a screenshot of the mostly-irrelevant first page.  Otherwise, I wouldn't worry about it—this is just how Sims 4 is built.
