Not sure if it's and ESO problem or an nVidia problem, but I finally got my GeoForce Experience working for ESO. I don't know if others have this problem as well but it seems from Google some people do and no fix was made yet. While it still doesn't show up in the game like it did before, but if I click on it first and let it load up then shut it down, then start ESO normally and it should work at least for me. If anyone knows a better way, please let me know, but this is how I get it to work. I know when I forget to click on GeoForce Experience on first it never starts up.
Once the Bethesda logos starts the square in the top right corner should show up the GeoForce Experience to show that it's activated for the game. If you don't see it, don't bother typing in your password, just exit out and start click on GeoForce Experience. Hopefully it will work. It is for me. Maybe this will help people who don't have it working yet.
