I dunno, once I got the Aero working, I'm practically living in it. The immersion is awesome. Nothing else was good enough to use in DCS, so I was using TrackIR, which was always a struggle to orient my head to see the right switches, and look up/behind in a furball, etc.
With Varjo Base 3.6.0.8, I'm mostly seeing a slightly softer display, nothing dramatic, so it's not bothering me. Which actually raises a question - I'm using the OpenXR toolkit and default resolution, which I expect is optimal for image clarity, and gets me 35-60 fps. But with the way VR wraps the image, I am still really confused about what the optimal render resolution should be, so I've been leaving it at the default. Everything looks really good, just a bit weird when I'm on the taxiway with other jets puttering around. Just wondering what other people are using for the resolution and what is supposed to be optimal (hopefully that's the default). If I'm not seeing a big difference with Varjo Base 3.6.0.8, maybe I didn't have it dialed in as much as I thought.
Other things that have popped up with Varjo Base 3.6.0.8 and the firmware update - my headset briefly popped up an overheat warning(!), but it went away almost immediately and was otherwise fine, and at one point it would black out for a few seconds at a time... always seemed to be when trying to land a helo, of course.... but a reboot has fixed that <knock wood>.
