They dont give us any 1:1 settings to see how much you "lose" by using the same settings either.

What they SHOULD do is:

"The fastest card was able to play at these settings (x) resulting in these performance numbers (1). Using the slower card at these settings (x) resulted in this performance (2). To achieve similar playability results we had to use these settings (y) on the slower card which resulted in these numers (3)."

No more BS.
