I’m extremely confused by all the talk of IPD. My understanding is that IPD has NOTHING to do with adjusting the FOV. I mean, it may affect it by a degree or 2, but the purpose of IPD adjustment is to keep your eyes in the sweetspot of the crappy fresnel lenses in the VR headset.
Surely the problem is a mismatch in the FOV of the rendered image, and the optical FOV of the headset?
If the software is generating a 110degree field of view, but your headset is only showing a 90 degree physical field of view (like my Reverb G2), then your cockpit will appear smaller, or zoomed out. Whilst I realise the C152 is small in real life, I estimate the yoke is only 7 inches across when looking through my headset. In reality, I believe it is close to 12 inches.
The answer is simply to zoom in slightly, but the facility has been disabled in VR mode.
If there are config file settings we could adjust, that might do it. I also find the default VR seated position is a little high. I’d quite like to adjust that too.
