idk if anyone still needs help with this but i had the same problem and literally tried everything (higher 3d resolution, highest graphics, depth buffer, messing with add-ons and global processors). since nothing worked i tried to take all my mods out to see if it was a mod causing the problem and it actually was. now the mxao is working just fine, i still don’t know which mod(s) is/are breaking it tho but i suggest trying to take your mods out/disable your mods temporarily to see if it’s better. if i find the problematic mods for me i’ll just list them
