Great, my friend ever tell that the potato fov is very small, but I never found it until yesterday. It look the fov is smaller on 120Hz , but they change the large and normal to be the same of 90Hz in new version, except potato still be same, it will be smaller in higher refresh rate (I found this and get super clarity).
I also found this
you will see neither normal nor small FOV is selected.
This technic can use with artisan too, when I change from 5k+ with potato to use artisan, it will get the potato fov on artisan, why it never have potato fov to be selected on artisan.
So I think some option can work on artisan, but pimax only lock some function.
I am thinking about testing large fov on 5k+ and swap to test on artisan, but I think may the large fov become normal fov like the potato fov which has more smaller fov.
