I came up with 13% based on what I had available to me, being 1% off doesn't seem embarrassing.
If you want to make enemies, try to change something.
why don't they just remove fov´until they've worked out all the cracks in it...
Given that pre-wipe and (intended) post-wipe fov differ significantly, it's hard to tell which one you have in mind. What is currently on is still engine default, but now equipped with wall check and few sneak reductions (in similar fashion to pre-wipe, just with different numbers). Bringing intended fov back should be matter of days.
...and I see nobody is trying fix it.
1. FOnline is created in the devs' sparetime, there is no 24/7 server maintenance service.2. How could you tell nobodies working on it?3. Just be patient.
5-6 hours is enough I think to turn-off new FoV, make rollback and turn it on.
