I googled this before and what I found was not too helpful. I also sent Bethesda the following email, they gave me some instructions, but they also recommended the forums so here was the email if any of you can help:
I recently got back into Skyrim when I got a new computer. I am now able to play the game with everything on maximum graphics, but for some reason the trees in the distance look blurry/unrendered. When I use the console command "tfc" I can go up close to the unrendered trees. (I attached images). I have my view distance on max and I tried to see if graphical mods would help, but they did not. With maximum graphics and graphical aid mods I shouldn't be able to see these unrendered trees, right? (and yes specifically trees) I could not find help in other places, but from what people have told me it could be a technical issue. I don't know what else to do or who else to turn to so I would appreciate it if you knew how to fix it. Thanks.
