"Great" trick cheating the menues - and cheating yourself. Cause yea, you enable FXAA and menue says FSR is on, too --- but actually FSR is not in effect anymore, doh!
quick note on workaround for those having seeming to not work follow same steps but be logged into character and be on
Display Setting-->DisplayQuality page
On this page click reset at top right will reset graphics only and load default optimal, now u can do the steps
Texture Quality --> your preference
click Lowest/Optimal click Remastered --> accept prompt
click Fidelity Super Resolution --> select preference of fsr quality
U can then save as custom slots bottom left and upload even to settings archive and archive download will still reapply fxaa. Hope this helps anyone still lookin for this or relooking up to remember as if u have already tried appying remastered with forced taa need to reset first.
