(Please Help!) My Graphics In UE4 4.10 are Terrible?

Hi guys, the graphics in my UE4 are horrible.
When I am editing & creating a material, the preview is fuzzy and shines. When In the play editor, all of the materials are fuzzy as well. When I press play, my character is blurry and is cloned on the ground, the lighting is blurry, and the framerate has constant drops.

My computer is a 2014 Retina Macintosh OSX 2.6 GHz Intel Core i5, 8gb memory 1600MHz DDR3.

Even when I put the settings on epic, the fuzz/noise is just even more dense.

Cloning glitch on epic mode:

Swap your grass textures for the Moss ground textures in the starter content, if the fuzzy effect goes away then your textures are to blame, make sure to swap the diffuse and normal and disconnect your AO and roughness during the test as well.

Thank you! I will try this.
Sorry for the late reply, I was working on other things.

This answer may help you as well:

If it isn’t your textures try the above and let me know if it works for either.
