Its been about 4 years since I upgraded photoshop. I finally got the latest version and I completely forget how to switch the setting off which creates these irritating little blocks when zoomed in on a texture. I thought it was under preformace in PS but Im drawing a blank.
I used google and search on here but I may have been wording my search incorrectly
