Hey Ralf,
Yes I’m aware of that. However this isn’t is that, as it only stutters when up close to items, or staring at a wall 3 feet in front of you in First Person mode. Not at all in open settings with trees buildings and people where normal framerate issues would occur.
Could be the mod, or something else by the sound of it. Perhaps the game itself doesn’t like its FOV changed the way its being changed.
Anyhow, its a non-issue, I only mention it for posterity in case others ran into it as well. If I determine what it is, I’ll update.
