Dip in graphic quality of late

I play GRB on Xbox One X .When I first got the X box the graphics seed amazing and I could see the enemy on the horizon where I could not so much on the old X box one.It was brilliant .Lately I have found the trees and bushes look almost 8 bit and the ground detail is not rendering well when playing CAS,

Does anybody else have this issue or is it just me? Is it just xbox or do PC players have the same issue.Graphics seem to have taken a big step back lately
