I don't know if this happened in previous versions of FI or not, as I can't specifically recall, but I've noticed suddenly that I'm seeing a border in my peripheral vision in FI that makes it look like I'm viewing the cockpit from inside a box. Both the left and right peripheral vision is restricted by a black border. I've tried to search the forums here to find out if this is normal, or if it's a problem, but apparently I'm either experiencing something that others haven't seen or noticed or I'm not phrasing my search question right (I assume the latter).
I've attempted to change the FI resolution, and that didn't do anything to solve this issue (although it kicked my frame rates much higher), but as of right now that's all I've done as I can't think of any other setting within FSX or FI that might affect this. I have recently upgraded my system to Windows 10 Pro with more RAM and a GTX 1080, but since I can't recall if I was experiencing this in my previous build or not I can't comment on whether that could be the issue.
To be clear, it's not a kill-all problem - it's only on the peripheral edge of the Oculus viewing area... but it's one of those things that once you notice it, you notice it all the time.
