One option is missing in your study::
"Texture Filtering" = Bilinear, Trilinear, Aniso 2x, Aniso 4x, Aniso 8x, Aniso 16x
Note that it is a different setting from the already here investigated "Texture Detail". Please, complete this excellent and extremely useful work by adding a Benchmark Framerate comparison and "slider comparison screenshots" also for this one.
Thanks for this information, it is helpful and amazing! Good Job!
