Hi RealDCSPilot,
I've come to this thread late, and actually had the Pico 4 purchased before reading this. Having had it for nearly 4 weeks, I agree with your sentiments of of this head set, and coming from a HP VR1000 (G1), its like night and day (once you include the Virtual desktop along with the package!)
Visuals are stunning because of the very large pancake lens, and I can see everything clearly in the pit, MFD's etc.
Turning you head to see a wingman or enemy in dogfight, the wide lens means you don't have to turn you head to get the target in the center, and you can scan the scene with your eyes for the attacker more easily without having to move your head. Same applies for getting to the back switches in the pit.
Tracking is excellent, and no loss of tracking in all my time using it, once the room is adequately illuminated.
Does not need windows mixed reality, which i found problematic with the G1, which has very poor tracking.
Pass through is amazing, allowing me to quickly find something on my desk quickly, and a double tap on the headset gets me back in the pit.
double click of the left controller menu button takes me back to desktop if i need to check/change anything (eg. forgot to start voice attack), Can be done with the controller leaving the mouse with the focus in DCS. Then double click to get back to DCS.
Headset is well balanced and light, but not perfectly comfortable for long sessions (there's accessories available to solve this), but much better that the old HP G1.
Wonderful headset for other stuff, and virtual desktop is easy to navigate (me (and family) having a blast with Half Life Alyx.
Screen door is not gone but to be honest once you can see the MFD stuff, you don't really notice it.
Wireless is great, but for simming i'll plug into a USB socket for charging. You will need to monitor it, since even socket charging does not keep up with the power usage.
Won't be beaten on price.
A year ago cancelled my order for the Varjo, and decided to put my money into a new rig, (from a 8700@5ghz & RTX2090ti, to a 13700K & 4090), I had a punt on this head set as an intermediate headset (as it wont be my last), and at the price it was worth trying out. Well i'm blown away with what it can do, and I havn't been back to 2D since I got it. I can't seem to stop just flying around in DCS, or dogfighting in BMS (where you can get an amazing stutter free experience).
And finally a note of caution. It does perform excellent with a very high end system, and will stand up to or be even better than others with the same resolution (Pancake over Fresnel any day), but with systems less than this there's going to be a bit of a dance to get the best from it. But VR has never been quite quite plug and play, so you should expect a little dancing.
