> I get 100% reliably with the first link, and got 4/5 on the cropped version so far.

Looking at whichfaceisreal, How much time do you have to spend on each decision, and would your success rate change if you didn't know in advance that exactly 1 of 2 was generated? It's easy to say 100% reliable, but I find myself really having to dig deep with my eyes to search for small tells* , which you have to know to do up front before you actually do it.

* - Often the tells are as minuscule as some ringing around the hair, which could just as easily be compression artifacts on a real photo.

For the first link (game.html), normally 5-10s, but much longer or shorter for some of them. For the second (game_cropped.html), it takes much longer, like a minute or so, except when the real image contains something distinctive StyleGAN2 can't do. For whichfaceisreal.com, which uses the original StyleGAN and only offers two options, none hand-picked, it takes me a second or two.
