I should do comparisons really but definitely (Think) I noticed a big difference after modifying some of the settings in the XML. However on my system it does use 8.2 GB VRAM now.
Still get 90+ fps (1080ti)
SMAA - true (Left taa still true)
SSRT_Shadows enabled - True
texture_streaming size - 4096
Motion blur - false
DoF - false
We really need a high resolution texture pack!
