Well, as said I believe FOV is very personal and depends on your IPD, and some other subjective factors.
I usually check this => https://risa2000.github.io/hmdgdb/ that is the “scientific” data for headsets.
Varjo Aero has => 110º horizontal degrees FOV, 70º overlap
Quest 3 has => 108º horizontal degrees FOV, 80º overlap
Pico 4 has => 104º horizontal degrees FOV, 104º overlap
Overlap is the angle that can be seen by both eyes. If it’s too small then you’ll see the black band in the middle (for example, when looking left, with your right eye and viceversa).
As you can see Aero and Quest3 have very similar horizontal degrees FOV, so they should be quite similar.
I’m quite sensible to overlap (black band in the middle) so that’s why I like Pico4. But I use Quest 3 too from time to time.
Virtual Destop is like ALVR, which is the open source based solution (and the app you’ve sent from steam seems to be based in it).
In a few 3-4 weeks, whenever U4 is released, you’ll be able to use OpenXR then, no more SteamVR and/or Oculus Runtime.
Just open Virtual Desktop Streamer, choose VDXR OpenXR Runtime and launch BMS. It will work nicely (I hope!) Plus, the quality with Virtual Desktop is IMHO much higher than with Oculus Runtime for the same resolution.
For the USB-C to RJ45 is, in a nutsell, connecting Quest3 to the router using a wired connection, instead wifi. It depends on what router you have and how far it is, but IMHO, it’s much better because latency, reliability (and I don’t have the router close to me!)
I posted the needed hardware here some time ago => https://forum.falcon-bms.com/topic/26165/quest-3-virtual-desktop-rj-45-adapter-working-without-wifi/3
Here is how it works with VD and Pico4 (same exactly for Quest3) =>
And here =>
Hope it helps!!
Kind regards
