"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!

It actually works, maybe my Instruction is not clear, Maybe. You will also feel the performance gain using the AMD-FSR than just Remastered Graphics.
