ENB's cause strange grid like pattern on most textures

[1Luv4SF]

I have grid lines on most textures in game and I know its from the ENB. I searched on this forum and was led to a fix of changing an ini setting in enbseries.ini. Under "SSAO_SSIL" I changed the value "UseSelfIntersecting = true" which was "false" before. It then removed all the grid lines on the textures, but tanked my FPS from 60 down to 40. What does "UseSelfIntersecting" do? Is there anything else I can do to fix this or is this just an engine level problem that all ENB's cause and is a take it or leave it kinda thing?

There is another thread about this that was up relatively recently......... I think texture was in the title...... enb was not, it was some setting or other, which I can't remember what it was.
