Hi! I'm using Arms 3 with my Oculus Rift (via VorpX) and in general I'm very happy with it. I think it is amazing how well it works for not having VR support built in. After fiddling with the resolution and FOV settings a bit I have almost no distortion when as infantry and in ground vehicles. The only problem I have its when flying helicopters. Somehow the FOV seems to be different in there and I have quite severe image distortions especially when rolling my head. Is there a way to fix this? By the way I already noticed the same problem when playing Arma 3 on a Monitor with Track IR, so it is not really VR related. Thank you very much for the help and best regards!

Helicopter FOV Changes on Airspeed Exceeds
derbismarck posted a topic in ARMA 3 - DEVELOPMENT BRANCH
There's a small config change that occurred which seriously screws with people trying to pilot helicopters in first person. You can see it here when I exceed about 30kph: This involuntary zooming screws with a pilots perception of airspeed and dimensionality. I don't think it's intended behavior. I made a small config change to fix this, which you can see in my post over here: It's just a matter of setting the default speedZoomMaxFOV value for class ViewPilot for all helicopters to be 1.0 as opposed to the now-default 0.75. -
I noticed an oddity with the new update (1.70) in relation to FOV changes and helicopter velocities and set out to fix it. I have that fix for you down below, but I'll also quickly explain the issue and how I got about fixing it for those who are curious. The problem: When you're piloting a helicopter (from first person) you get a noticeable FOV decrease (seen visually as an involuntary "zoom in") if you exceed a certain airspeed in some airframes. This FOV decrease can be very jarring, as it interferes with a pilot's intuition in a specific airframe and with their ability to judge distance, velocity, and dimensionality at a glance. I have a sample video here that shows off the issue. It may not look too terrible when watching someone else, but if you're reasonably proficient with any given airframe and attempt to take it up in this update you will immediately see what I mean. How I fixed it: I first tried looking through the config.cpp for air_f.pbo, but couldn't spot anything obvious on a simple first pass. I instead took that config.cpp from 1.70, and the same config.cpp from 1.68 and did a file comparison. From there it was easy to guess which config change introduced the FOV issue. I then quickly wrote up a config addon to remedy this issue for my own singleplayer shenanigans. Here's the source for the config fix: class CfgVehicles { class AllVehicles; class Air: AllVehicles { class ViewPilot; }; class Helicopter: Air { class ViewPilot: ViewPilot { speedZoomMaxSpeed = 1000000; }; }; }; And finally here's a download for the PBO that does the fixing: https://www.dropbox.com/s/l05796h0v1c55vl/bsm_helo_fov_fix.pbo
